It is a common understanding in psychoacoustics that the ear cannot respond to sounds at such high frequency via an air-conduction pathway, so one question that this research raised was: does the hypersonic effect occur via the "ordinary" route of sound travelling through the air passage in the ear, or in some other way?
More than 1.8 million people claim noisy neighbours have made their life a misery and they cannot enjoy their own homes. The impact of noise on health is potentially a significant problem across the UK given that more than 17.5 million Britons (38%) have been disturbed by the inhabitants of neighbouring properties in the last two years.

An audio frequency or audible frequency (AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz.
A systematic review and meta-analysis published in 2022 recorded an increased prevalence of risk of hearing loss compared to 2015 estimates among young people between 12 and 34 years of age who are exposed to high sound pressure levels (SPL) due to use of headphones and entertainment soundscapes.

A long-range acoustic device (LRAD), acoustic hailing device (AHD) or sound cannon is a specialized loudspeaker that produces sound at high power for communicating at a distance. It has been used as a method of crowd control , which has caused permanent hearing damage , having an extremely high decibel capacity (up to 160 dB measured at one ...
Cargo ships generate high levels of noise due to propellers and diesel engines. [79] [80] This noise pollution significantly raises the low-frequency ambient noise levels above those caused by wind. [81] Animals such as whales that depend on sound for communication can be affected by this noise in various ways.
