An equal-loudness contour is a measure of sound pressure level, over the frequency spectrum, for which a listener perceives a constant loudness when presented with pure steady tones. [1] The unit of measurement for loudness levels is the phon and is arrived at by reference to equal-loudness contours. By definition, two sine waves of differing ...
Sensorineural hearing loss ( SNHL) is a type of hearing loss in which the root cause lies in the inner ear, sensory organ ( cochlea and associated structures), or the vestibulocochlear nerve ( cranial nerve VIII). SNHL accounts for about 90% of reported hearing loss. [citation needed] SNHL is usually permanent and can be mild, moderate, severe ...

Otorhinolaryngology, audiology. Noise-induced hearing loss ( NIHL) is a hearing impairment resulting from exposure to loud sound. People may have a loss of perception of a narrow range of frequencies or impaired perception of sound including sensitivity to sound or ringing in the ears. [1] When exposure to hazards such as noise occur at work ...
During extreme cold events, you may hear a loud boom and feel like you have experienced an earthquake. However, this event was more likely a cryoseism, also known as an ice quake or a frost quake ...
The Sun is said to be extremely noisy, but we can’t hear it since sound doesn’t travel through space. Scientists at the University of Sheffield decided to use vibrations within our star's ...
Upsweep is an unidentified sound detected on the American NOAA's equatorial autonomous hydrophone arrays. This sound was present when the Pacific Marine Environmental Laboratory began recording its sound surveillance system, SOSUS, in August 1991. It consists of a long train of narrow-band upsweeping sounds of several seconds in duration each.
Elevated workplace or environmental noise can cause hearing impairment, tinnitus, hypertension, ischemic heart disease, annoyance, and sleep disturbance. [ 3][ 4] Changes in the immune system and birth defects have been also attributed to noise exposure. [ 5] Although age-related health effects ( presbycusis) occur naturally with age, [ 6] in ...
