Temporary threshold and loudness shifts: Frequency patterns and correlations

Abstract: Two experiments studied the frequency pattern of TLS (temporary loudness shift) as a function of the level and frequency of the fatiguing sound. In experiment 1, the fatiguing tones were intermittent 375-, 1500-, or 3000-Hz tones (10 s on/10 s off) at 75, 80, 85, 90, or 95 dB SPL. The TLS patterns were established for a continuous, 60-phon test tone at different frequencies presented simultaneously with the intermittent fatiguing tone. In experiment 2, a 1000-Hz exposure tone with an intermittency of 10 s on/2… Show more

“…Thus, the effect of the sensitivity enhanced level in the central system is considered to be relatively low when the previous sound having over 80 dB SPL is presented in the ipsilateral ear. And many studies of auditory fatigue employed over 100 dB as the previous sound SPL [8][9][10][11], therefore, the sensitivity enhancement effect in the central system was not observed but the rising of the threshold increase level was observed in the ipsilateral ear by the sensitivity deteriorated effect in the auditory peripheral system.…”

“…Also, the absolute threshold of hearing becomes higher when a loud previous sound is presented to the ipsilateral ear. This phenomenon is known as ''auditory fatigue [8][9][10][11].'' The threshold increase level of auditory fatigue becomes larger as the sound pressure level (SPL) of a previous sound increases [18].…”

“…The response of the human auditory system to overstimulation has been addressed in experiments using pure tone exposures [1,2,3,4,5,6,7,8], different types of band-pass and broad-band noise [9,10,11,12,13,14], and impact and intermittent noises [15,16,17]. The exposure Received10August 2010, accepted 29 May 2011 levels vary from 20 dB SPL [5] up to 125 dB SPL [4] with exposure times ranging from minutes to days [10].…”
