#decibels

• Deafening — Deafening, producing a noise of extreme intensity, strident, sharp, or tumultuous, which far exceeds the acoustic comfort threshold of the human ear. In an extended stylistic sense, it describes a phenomenon, success, or public reaction of overwhelming and undeniable scale.
• Audiogram — A graphic representation of an individual's hearing capacity, obtained through an audiometric test, which indicates the minimum threshold of sound perception across various frequencies for each ear. The chart correlates sound intensity in decibels with wave frequency in Hertz, serving as the core clinical tool to diagnose hearing loss.
• Audiometry — A clinical method of measuring hearing acuity and sensitivity using a device called an audiometer, by determining the perception threshold of sounds at various frequencies and intensities. The procedure enables professionals to diagnose the type, degree, and anatomical location of hearing loss.
• Audiometer — An electroacoustic high-precision device used in medicine and audiology to measure hearing acuity and determine the threshold of sound perception. The apparatus generates reference sound signals with strictly controlled frequencies and intensities transmitted via specialized headphones, allowing the practitioner to map out hearing loss.
• Hearing protector — Personal protective equipment designed to attenuate ambient noise levels and protect the auditory system against acoustic traumas; ear protector. As an adjective, it describes a device, soundproofing material, or substance capable of diminishing harmful acoustic wave intensity.
