In fact, a well-established clinical sign of noise-induced hearing loss in pure tone audiometry is the presence of a temporary or permanent threshold shift, with the notch at 4 kHz.
At 6 months, 4 of them (16%) still exhibited bone-conduction deterioration, and they were considered to have experienced a permanent threshold shift.
Repeated TTSs over weeks, months, and years fail to recover completely and thereby become a permanent threshold shift (PTS).
However, the high peak impulse levels of all the three bat materials could be a potential hazard for a temporary threshold shift, permanent threshold shift, or other related symptoms if this level is met with repeated exposure in a single game with multiple at-bat opportunities or during a batting practice scenario.
When the sound is sufficiently intense, it produces a much more severe temporary threshold shift which may go on to become a permanent threshold shift. There is a critical point at which moderate TTS changes to long term PTS, which correlates with anatomical damage to the outer hair cells.
He found that 68% of 806 postdeployment evaluations had been diagnosed for at least one of the following: acoustic trauma (5.6%), permanent threshold shift (29.3%), tinnitus (30.8%), eardrum perforation (1.6%), or moderately severe hearing loss or worse (15.8%).
Repeated exposures that result in a TTS may eventually lead to a permanent threshold shift (PTS).
If any of these symptoms sound familiar, and if you have a history of noise exposure, you may be developing or already have a noise-induced permanent threshold shift, or NIPTS, as many call it.
The blast did not rupture the tympanic membrane, but it appeared to have caused a permanent threshold shift at 4 kHz.
(21) The authors reported that permanent threshold shifts occur at 250 Hz and above and that the low frequency range was affected most, when compared with normative data.
