Temporary threshold shifts produced by exposure to low-frequency noises.
Groups of human subjects were exposed for 8 or 24 h to an octave-band noise centered at 63, 125, or 250 Hz. For a 24-h exposure at 84 dBA, temporary threshold shifts (TTS) increased for 8-12 h and then either decreased or remained constant. Although TTS was less than 20 dB, complete recovery for many of the subjects required as long as 48 h. Accordingly, the higher level exposure which was plan...
متن کاملTemporary Auditory - Threshold Shifts Induced
Four divers were exposed successively for ten minute periods to pure tones of 5600, 1400, and 700 hertz (Hz) (in that order) in air at 100 decibels above 20 raicropascal and in water at various sound pressure levels between 125 and 150 decibels above 20 micropascal. Divers incurred moderate temporary auditory-threshold shifts (TTS) from all exposures. Equivalent amounts of TTS are produced in w...

regarding the ever evolving and improving world on different aspects of knowledge, the need to a worldwide communication would emerge stronger than ever before which calls for special attention on the judgments and best choices for intermediating between the nations. as the language skills for translation are tested separately from translation skills themselves, to assess translation skills pro...
Hearing threshold shifts and recovery after noise exposure in beluga whales, Delphinapterus leucas.
Temporary threshold shift (TTS) after loud noise exposure was investigated in a male and a female beluga whale (Delphinapterus leucas). The thresholds were evaluated using the evoked-potential technique, which allowed for threshold tracing with a resolution of ~1 min. The fatiguing noise had a 0.5 octave bandwidth, with center frequencies ranging from 11.2 to 90 kHz, a level of 165 dB re. 1 μPa...
متن کاملTemporary threshold shifts in fingertip vibratory sensation from hand-transmitted vibration and repetitive shock.
Temporary threshold shifts (TTSs) in vibrotactile perception produced by continuous vibration and repetitive shock have been investigated. Subjects were exposed to vertical hand-transmitted 100 Hz continuous vibration and various repetitive shocks of equal energy content formed from one complete cycle of a 100 Hz sine wave. The repetition rate of the cycles was 5, 25, 50, or 100 s-1 while the r...
