"This 1940s old as dirt med school classic video describes how humans hear sound and how the human ear works. The video covers the anatomy and physiology of the ear and discusses the outer ear, the middle ear and the inner ear. Other topics include the eardrum (tympanic membrane), hammer (malleus), anvil (incus), stirrup (stapes), organ of corti, and the cochlea. Included in the video is a labeled diagram showing the parts of the human ear. This is excellent information for managers who have workers exposed to high levels of noise that could potentially damage hearing."

"Psycho-Acoustics: Sound Control, Emotional Control, and Sonic Warfare" explores the work of former Stevens professor Harold Burris-Meyer whose research in the mid-twentieth century investigated the use of sound as a tool for emotional and physiological control and played a critical role in the emerging fields of sound design for theater, music for industry, and applied psychoacoustics for warfare."

The project set out to give a rich and rigorous account of human perception of and response to soundscapes. To do this it used overlapping methods from a wide range of disciplines, ranging from the quantitative (e.g. acoustics) to the qualitative (e.g. social science) to the creative (e.g. sound art). Qualitative fieldwork (soundwalks and focus groups) determined that people conceptualised a soundscape into three components: sound sources (e.g. a market), sound descriptors (e.g. rumbling) and soundscape descriptors (e.g. hubbub). Lab-based listening tests along with the fieldwork have revealed that two key dimensions of the emotional response to a soundscape are calmness and vibrancy. In the lab these factors explain nearly 80% of the variance in listener response. Interview responses from real soundscapes further indicate that vibrancy can be expressed in two sub-dimensions expressing variation over time and over sound mix. Physiological validation of the main dimensions is provided by images of changes in the brain during listening from fMRI scans and by changes in heart rate. Artistic work and the public responses to it illustrate the huge range of sounds and soundscapes considered positive. Tools for simulating soundscapes have been developed and seem to be effective for several purposes, including design and public engagement - that is, sound play. The project results will lead to new metrics and assessment methods for soundscapes, new ideas for design and user engagement and, perhaps, better policy on environmental noise.

"In fact, listening to that one song -- "Weightless" -- resulted in a striking 65 percent reduction in participants' overall anxiety, and a 35 percent reduction in their usual physiological resting rates."

" Science of storytelling 5 identified specific sounds that filmmakers use to scare us in horror-thriller films. In this article, I will be revealing the science of how different sounds in horror-thriller films optimise engagement. The research findings are based on a 5-year scientific study of suspense and engagement in horror-thriller films. I will first summarise the film experiment research methods and how our brain responds to a fear stimulus through a chain of neurological processes that can be recorded and analysed. Finally, the research outcomes (highlights) describe how viewers physiologically responded to specific sounds in horror-thriller films, in terms of anxiety durability (time) and intensity (level)."

"On the sensations of tone' brings together three artists where sound, listening, the ear of the listener and the composer are essential elements in their work. This approach evokes the theories of Hermann Ludwig von Helmholtz (1821-1894) in his seminal work 'The physiological theory of music based on the study of auditory sensations', published in 1865 in Germany."

"THLEEP; Therapising For Sleep; a series of sound and light investigations; combined as a synaesthesia to reduce anxiety and promote healthier sleep cycles. We explore the combination of neuro-acoustics and vision physiology, and present installations & performances as a supplement to daily requirements for the positive frequencies of light and sound - helping regulate our lives."

"Montefiore Hospital in the UK teamed up with ambient music artist Brian Eno in April 2013 to create a Quiet Room where patients can find relaxation and calm. Eno designed a light and sound installation for the room and for the reception area, including an original soundtrack of soothing instrumental tunes. Once the room has had a few inhabitants, there are plans to examine whether the patients who have sought solace there exhibit any beneficial physiological changes."

"   "Blissful positive energy," "Full chakra healing," "Extremely powerful third eye opening" - such are the benefits of binaural beat listening as promised in the titles of a few popular YouTube videos.[1] Throughout the wide distribution network of binaural beat audio, discourses abound that purport effects such as heightened sexual arousal; improved performance at job interviews; psychedelic-like drug experiences; enhancements in creativity, IQ, and lucid dreaming; and assistance in the fight against cancer. More than a panacea, binaural beats and the meditative auditory experience the associated rhetoric claims they provide, do not just heal or prevent defect and injury; they heighten the overall quality of life. Or, so is the promise.  "

"Ears are a peculiarly individual piece of anatomy. Those little fleshy seashells, whether they stick out or hang low, can be instantly recognizable in family portraits. And they aren't just for show. Researchers have discovered that filling in an external part of the ear with a small piece of silicone drastically changes people's ability to tell whether a sound came from above or below. But given time, the scientists show in a paper published Monday in the Journal of Neuroscience, the brain adjusts to the new shape, regaining the ability to pinpoint sounds with almost the same accuracy as before."

"Sound affects every aspect of our lives - even in our communication. I want to talk in this short blog about the ways sound affects us. You can listen to the blog or read the transcript below."
