  • The Benefits of Acoustic Treatment in Schools

    Despite the prevalence of environmental noise pollution in schools and the profound, wide-ranging, and long-term harms chronic exposure can inflict on children and adults alike, there is hope. The evidence suggests that acoustic treatment can be highly effective in preventing excessive environmental noise and its associated physical, academic, and psychosocial harms. Studies have shown that classroom refurbishments, which include environmental sound mitigation, have contributed to significant improvements in students’ listening and attentional capacities, in teachers’ voice ergonomics, and in the overall sense of physical and mental well-being in both students and teachers (1, 2). It is for this reason that classroom acoustics are becoming a key priority in the design and construction of new schools and the renovation and refurbishment of existing ones. In response to the growing demand for sound mitigation, agencies, such as the EPA, and environmental accrediting bodies, including LEED certification programs through the US Green Building Council, have established standards for ensuring healthy and safe sound environments for children and educators in school environments. For instance, the EPA has recommended ideal sound levels of 45 decibels or less on average for eight hours per every 24 hours in schools, hospitals, and private residences. Initiatives such as the Well Building Certification program and the Armstrong Living Building Challenge have also emerged to promote optimal learning environments through design and materials innovation, including supporting novel approaches to sound mitigation and acoustics optimization. Likewise, an array of state and local initiatives are emerging nationwide to support students’ and teachers’ health and performance on campus, including California’s Green Building Code, which has mandated acoustic treatment in all California public schools since 2011. Although standards have been created, and there are ongoing initiatives to improve learning environments, noise pollution is inherently part of most schoolhouse environments. We know noise pollution in the classroom inhibits academic performance while impairing the physical, emotional, and mental health of children and teachers alike (3, 4, 28, 29). With all of the remote learning over the last three years, our children and teens are more sensitive than ever to large group interactions with loud sounds. So what will it take to get effective acoustic treatment in school environments to remediate the diverse harms associated with ambient noise pollution? Re-envision the Classroom We understand how constrained designers are by budget and how value engineering often cuts things like acoustic treatments. However, optimal learning environments don’t happen accidentally. They must be created intentionally, and maintaining healthy noise levels requires sound mitigation and acoustics optimization. Below we are going to explore the many reasons acoustics need to be elevated as a priority for healthy nervous system development of the kids attending schools and those teaching them. When you are asked to envision the stereotypically noisy working environment, the first sites that probably spring to mind are industrial factories stuffed with heavy machinery or crowded airports with screaming jet engines perpetually overhead. Studies show, however, that when it comes to environmental noise pollution, nursery, primary, and secondary school classrooms rank near the top (2, 3, 5, 6). When a classroom is full of children playing or talking, levels can even reach up to 95 dBA, far beyond the recommended 45 dBA average and higher than the 90 dBA recommended maximum. This means that day in and day out, children and educators alike are being asked to perform in less than ideal conditions, to pursue developmental, cognitive, and academic milestones that may well establish the child’s entire life trajectory, in environments that are likely to not only inhibit their success but also to incite tangible harms. The Physical Effects of Classroom Noise Exposure If you’ve ever spent an extended amount of time in a noisy environment, you’re probably already quite familiar with the physical toll this can take. Environmental noise exposure has been associated with a host of negative physical impacts, including stress-induced spikes in blood pressure, respiration, heart rate, and muscle tension (7, 8, 9, 10). Long-term exposure to environmental noise has also been shown to increase the risk of tinnitus and hearing loss in both children and adults (11, 12, 13). Psychosocial Harms Unfortunately, the risks to children and teachers from long-term exposure to environmental noise extend far beyond the physical. There is mounting evidence that chronic noise exposure can have a devastating impact on mental health, increasing the risk of depression, anxiety, and sleep disorders in affected persons (14, 15, 16). For children, the research suggests, these harms can linger well into adulthood due to the functional and structural changes wrought by chronic noise exposure on the child’s developing brain (15, 16). But environmental noise doesn’t just affect children’s sense of happiness, peace, and well-being. It has also been shown to undermine their capacity for forming healthy relationships with adults and peers and may even contribute to the development of behavioral and cognitive disorders, including ADHD, emotional hyperreactivity, and poor impulse control (17, 18, 19, 20). Given the significant harm that prolonged noise exposure can have on children’s mood, behavior, and attention, it is perhaps no surprise that it should also be associated with steep declines in academic performance (4, 21, 22, 23). The research also indicates that these detrimental impacts are particularly acute for children with special needs and for second language learners (24). Perhaps no population is more vulnerable to the adverse effects of classroom noise, however, than students who are on the autism spectrum or who have sensory processing disorders (25, 26, 27). For these children, hypersensitivity to environmental stimuli means that environmental noise can quickly transform the classroom from a place of learning, support, and caring into a place of confusion, chaos, and even terror. An Acoustic Champion The long-term impacts of noise are subtle and difficult to understand since they are not direct or easy to trace. The good news is that science is elevating the importance of acoustic treatments and prioritizing sound absorptive materials. School projects also need an acoustic design champion, someone who understands the critical nature of a good acoustic design and presents the case studies to ensure it doesn't get cut from the project.

  • Selective Hearing or Acoustic Distraction

    Of all the human senses, the sense of hearing may be the most autonomous, the least controllable. After all, we can shut our eyes to sights we do not want to see. We can hold our breath, at least for a while, to block noxious odors. We can even recoil from the sensation of touch. But, short of walking around with ear plugs or our palms planted firmly over our ears, we can’t really turn off the sense of hearing. That doesn’t mean, though, that we’re entirely powerless against the sounds that surround us. Indeed, our bodies house some pretty sophisticated machinery for helping us to hear what we want to hear–and to shut out what we don’t. Yes, selective hearing is a real thing, and it often occurs without your even realizing it. But what is selective hearing, exactly, how does it work, what does it do for us, and what about when it doesn't work as it should? Selective Hearing Although there are some important overlaps, the mechanisms and the functions of selective hearing differ in significant ways from hearing filters and other auditory processing systems. For example, while auditory processing is principally a physiological occurrence, selective hearing results from the interplay of an array of factors, including the psychological, the motivational, and even the visual. In other words, selective hearing illuminates the reality that what we hear isn’t just determined by the environmental noises that encompass us. Rather, what we hear is often based largely on what we want to hear. Selective Hearing, ASD, ADHD, and Sensory Processing To be sure, selective hearing processes are informed largely by our feelings and our goals, but that does not mean that we have complete control over what we “select” to hear. This is particularly true for persons with neurocognitive disorders. In a study of “listening difficulties” among school-aged children, Dillon and Cameron (2021) have found that children experiencing difficulties in speech, learning, or behavior are often encountering an array of challenges relating to focused hearing, speech differentiation, noise filtering, attention, and memory (1). In other words, these children are unable to engage in healthy selective hearing processes. Such obstacles may relate to a host of neurocognitive conditions, from autism spectrum disorder (ASD) to attention deficit hyperactivity disorder (ADHD) to sensory processing disorder. A growing body of evidence suggests, for example, that multisensory processing disorders may well be a distinguishing feature of the autism spectrum (2, 3, 4). For persons who are neurodivergent, such as those who have sensory processing disorders or those on the autism spectrum, sensory stimuli don’t always help to organize, understand, and experience the world. All too often, auditory, visual, and tactile input can become an overwhelming, disorienting, and disturbing chaos of sensations. In such situations, selective hearing processes often rapidly shut down, and the person is subsumed by a sea of noise. This is an example of the critical importance of environmental sound mitigation. Whether in the healthcare, academic, or residential setting, noise reduction efforts can help neurodivergent persons be more comfortable, productive, and highly functioning, enabling them to enjoy a higher quality of life overall. A Baby’s Cry Perhaps the most significant illustration of the reality of both hearing filters (physiology) and selective hearing can be found in humans’ responses to infants’ cries. Research studies demonstrating the exceptional capacity of adult humans, and particularly women, to recognize and automatically respond to the sound of a crying baby are plentiful (5, 6, 7). These studies also indicate that important differences exist between men and women and between parents and nonparents in the capacity to recognize an infant’s cry, to differentiate their own child’s cry from the cries of another child, and to react in a positive manner (i.e. by picking up, feeding, or otherwise soothing) manner to the infant’s cry (6, 7, 8). Research into gender differences in infant cry responses has found that women are more likely than men to awaken from sleep or to experience disruptions in their train of thought when a child begins to cry. While the consistency with which differences in gender and parental status impact a person’s recognition of and response to an infant’s cries might seem to indicate purely biological mechanisms at work, some confounding evidence has also emerged. There is, indeed, substantial evidence that speaks to the role that psychological and motivational factors play in determining what, exactly, it is that we hear in the world around us. For example, in a study of young adults’ responses to infant cries, Kim et al. (2015) found that young persons who had been reared in poverty were less likely than the general population in the same age cohort to respond positively to a newborn’s cries and were more likely to feel annoyed and, therefore, less inclined to respond with caregiving to the child (9). Life experiences don’t just seem to shape what you hear and how you respond, but they may also inform how well we hear. Again, infant cry research is telling here. For instance, in a study of infant cry recognition and response in mothers who had previously received infertility treatment, Sampei and Fujiwara (2020) found that women who had been treated for infertility reported a higher frequency of crying than did new mothers who had not received infertility treatment (10). This suggests an amplified sensitivity to the sounds of their crying child, a sensitivity that cannot be explained purely by physiology but that probably has deep roots in emotion, experience, and motivation (i.e. in the domain of psychology). In other words, selective hearing has a great deal to do with your life experiences, how you feel, what you want, and what you’re trying to do. If one is young and poor and trying to figure out how to buy food for the week, they may not hear their child’s cries at all. If they have maltreatment in their own childhood or if their own distress cries had gone neglected or unheard, the same negative selective hearing response may occur with their own children (11). On the other hand, if you have had to struggle to conceive a child, if your capacity to ever become a parent has been in doubt, then the research suggests that you are likely to be particularly alert and responsive to your child’s cries. The Eyes (and the Ears) Have It As important a role as emotions, experience, and motivation all play in selective hearing, these are not the only factors at work. Indeed, when it comes to determining what and how you hear, your eyes may be every bit as important as your ears. In fact, the connection between vision and hearing seems to be so profound that researchers and clinicians in the field of audiology are developing technologies to integrate visual cues into hearing technologies for persons with and without hearing loss (12, 13, 14). Specifically, researchers have found that hearing aids that incorporate eye gaze technologies provide significant benefit to typically hearing and hard of hearing persons in regard to speech recognition and voice differentiation in crowded, noisy environments with multiple, overlapping, and simultaneous conversations occurring. The benefits persisted even when the speaking subject was in motion, provided that the hearer was able to visually track the speaker, even in low light conditions. In essence, even the most minute and subtle of visual cues will affect what and how we hear because the world around us is not fixed. Rather, it is the construction of our consciousness, and that derives from the interaction of our physiology, our psychology, our life histories, and our senses. However, because it is not always possible to effectively visually track the source of the sound you are trying to selectively hear, persons who are hard of hearing do not always benefit from the nexus between hearing and sight. Once again, this is why the listening environment is so critical. Particularly in conditions of overlapping sound, persons with hearing loss can find it difficult or impossible to filter out background noise and gain sound clarity from the subject at which they’re directing their attention. The good news, though, is that it’s possible to mitigate the effects of what researchers term the “cocktail party effect” through environmental noise mitigation, such as the use of noise reduction wall panels and ceiling tiles. As acoustic reverberations are absorbed and minimized, those with hearing challenges will be better able to fix their attention to the sources of the sounds they want to hear. This is true even where visual tracking isn’t feasible. In crowded office environments where multiple conversations are often occurring at once, for example, environmental sound mitigation can mean all the difference for employees, clients, and stakeholders with hearing challenges.

  • The Soundtrack of Life Around Us

    If your life had a soundtrack, what would it be? We’re not just talking about the music you love, the songs that seem to encapsulate a particularly memorable time in your life, though these are certainly important. What about the other sounds that permeate, shape, and define your world and your life’s experience? Would it be the peaceful sounds of wind in tree leaves and birds chirping, the restful sound of flowing water, or the joyful sounds of children’s laughter and energetic chatter? Or would it be the incessant rumble of traffic outside? Would it be the clickety-clack of keyboard keys? The shriek of industrial machinery? Perhaps you drown out the noise around you and create your own sound environment with your favorite music. The fact is, most of us pay little attention to the myriad and unceasing ambient noises that fill our daily lives. That’s a pity because the sounds that surround us don’t just characterize our environment, but they also exert a profound impact on our overall quality of life. It’s little wonder, then, that many of the world’s ancient religions perceive the universe and life as we know it to have originated not in physical matter but in sound. In Buddhism and Hinduism, everything that exists evolved from a single syllable: Om. Christianity and Judaism both teach that, in the beginning, was the Word. Indeed, the belief in the life-giving and life-sustaining power of sound is perhaps as old as human civilization itself. Modern science is increasingly able to confirm what the ancients knew: that certain sounds possess tremendous power. Nature’s Solace If you’re asked to identify the sounds that make you feel the happiest and most peaceful, the odds are that sounds derived from nature are going to populate your top ten list. Consider the rhythmic sound of ocean waves, the joyful tones of birdsong, the lulling sweep of the wind through the trees, and the soothing chips of summer crickets in the night. Our world is teeming with the sounds of life, and it’s perhaps little wonder that our physiological and psychological selves are designed to respond to them. Indeed, there is abundant evidence that exposure to natural sound can produce significant physical and mental health benefits (1, 2, 3, 4). The effects are so significant, in fact, that researchers have found that even simulated nature sounds can generate demonstrable improvements in cognitive functioning and overall mood. For example, in a study of the effect on university students of exposure to natural sounds via mobile phone application, Luc et al. (2021) found that daily use of the app substantially improved the subjects’ working memory, attention, and reaction times (5). The researchers also found that these students experienced an enhanced sense of well-being and optimism and a more positive affect overall (5). Similarly, Thoma et al. (2018) found that exposure to water sounds can substantially decrease cortisol levels, even in conditions of acute stress (6). In their study, the researchers subjected women with a history of somatic complaints, who were otherwise healthy, to a stressful psychosocial task. The experimental group, which was made to complete the exercise after a period of listening to simulated water sounds, performed significantly better and exhibited a substantially decreased physiological stress response than the control group, which was not exposed to water sounds (6). The benefits of nature sounds don’t end there, however. There is mounting evidence that the sounds of nature may act on both the sympathetic and parasympathetic nervous systems in highly beneficial ways, even when the subject is not actively listening. Studies suggest, for example, that patients undergoing surgery or other invasive procedures fared better during and after the procedure when they were exposed to natural sound (7, 8, 9, 10). These results were consistent across patient populations, with enhanced healing demonstrated by patients exposed to nature sounds under both full and partial sedation. The Power to Soothe As profound as the physical and mental health benefits of nature sounds may be, these are far from the only categories of sound that can restore and revitalize your well-being. Indeed, the evidence in support of the positive impact of listening to music is vast and growing (11, 12, 13). Studies have shown that listening to certain types of music can substantially improve cardiovascular health, boost immunity, increase exercise adherence, enhance quality of life, and improve overall mental health (11, 12, 13, 14). Likewise, in a study of patients undergoing orthopedic surgery with spinal anesthesia, Azi et al. (2021) found that those who were exposed to music during the surgical procedure required less sedation, felt less anxiety, and had a more positive experience in general than the control group (15). Another recent and deeply exciting advancement in the effort to understand the mechanisms through which music aids health and healing is the discovery of so-called “human-auditory entrainment” (16). This term refers to new insights in the field of neurobiology into the impact of auditory processing on bodily systems. More specifically, researchers have found that the auditory processing of musical rhythms can have a significant therapeutic effect on the human motor system, particularly for those with neurological and motor disorders. Studies suggest that music listening therapy may significantly improve gross and fine motor function in patients with movement disorders, including those with conditions such as Parkinson’s disease, stroke, cerebral palsy, and traumatic brain injury (l6). With these new realizations, what would your soundtrack of choice be? We would like to hear from you, whether it's a specific song or particular sounds in nature, what helps you feel relaxed, calm, and at ease?
