For example, very curvy ear canals, narrow ear canals, or surgical ears are more prone to earwax buildup. When wax builds up, it causes muffled hearing, tinnitus, or aural fullness (plugged-up ...
As video games flourished and became increasingly common, however, amateur game designers began to adapt video games for the blind via sound. In time audio game programmers began to develop audio-only games, based to a smaller and smaller degree on existing video game ideas and instead focusing on the possibilities of game immersion and ...
Using both ear muffs (whether passive or active) and earplugs simultaneously results in maximum protection, but the efficacy of such combined protection relative to preventing permanent ear damage is inconclusive, with evidence indicating that a combined noise reduction ratio (NRR) of only 36 dB (C-weighted) is the maximum possible using ear ...
These vibrations result in an increase in the metabolic demands of the auditory system. During exposure to sound, metabolic energy is needed to maintain the relevant electrochemical gradients used in the transduction of sounds. The extra demands on the metabolic activity of the system can result in damage that can propagate throughout the ear.
A sound test is a function built into the options screen of many video games. This function was originally meant to test whether the game's music and sounds would function correctly (hence the name), as well as giving the player the ability to compare samples played in Monaural , Stereophonic and later Surround sound.
The outer ear pathway corresponds to the sound pressure generated in the ear canal cavity due to the vibration of the ear canal wall, which constitutes the source of the occlusion effect. At low frequencies, the outer ear pathway is negligible when the ear canal is open but dominates when it is occluded.
RealSound is a patented (US US5054086 A) technology for the PC created by Steve Witzel of Access Software during the late 1980s. [1] RealSound enables 6-bit [2] digitized pulse-code modulation (PCM)-audio playback on the PC speaker by means of pulse-width modulation (PWM) drive, allowing software control of the loud speaker's amplitude of displacement.
Diver clearing ears Section of the human ear, the Eustachian tube is shown in colour. Ear clearing, clearing the ears or equalization is any of various maneuvers to equalize the pressure in the middle ear with the outside pressure, by letting air enter along the Eustachian tubes, as this does not always happen automatically when the pressure in the middle ear is lower than the outside pressure.
