Noise and its after-effects: A brief review of auditory plasticity

Susan Rogers, PhD, Berklee College of Music.

October 2015, 139th AES Convention, New York, U.S.A.

Susan Rogers presents a summary of new research works about noise induced hearing loss (NIHL). Threatening noise, traumatic noise, active and passive listening. “Compressed music delivered by most portable music players is closer to noise than the original music because the overall intensity of the whole spectrum is higher. This global increase and the disappearance of quiet transients could harm the auditory system on a long-term basis.”

Give Peaks a Chance

New regulation to prevent hearing loss from the use of personal media players also has the effect of attenuating hyper-compressed content. Limiters and compressors are great artistic tools, but remember to judge at equal loudness. Information about Nordic Dynamic and “MusicTester” are featured in this presentation.
