Sentence examples for permanent threshold from inspiring English sources

The permanent threshold shift was also calculated by means of Robinson's method and ISO's method.

"More importantly, with more frequency in these episodes of exposure, the 'temporary threshold shift' can become a permanent threshold shift and a permanent hearing loss".

The rats were then exposed to a noise designed to induce 20 40 dB of permanent threshold shift.

The conditioned animals showed reductions in permanent threshold shift and reduced inner hair cell loss relative to controls.

The proposed instrument would enable collection of data for validation of presently defined and yet to be defined metrics quantifying noise-induced permanent threshold shifts (NIPTS) resulting from impulse/impact exposures.

Auditory brainstem response thresholds were measured pre-exposure and several times post-exposure (i.e., 0 27 days) to determine the magnitude of the temporary threshold shift (TTS) and permanent threshold shift (PTS).

Often traumatic brain injury is associated with sound overpressure damage to the cochlea, such as munitions explosions, which can lead to permanent hearing threshold elevation.

Even before testing in humans, data in animal models, such as guinea pigs, identified direct correlations between decreased serum magnesium levels and harmful noise-induced permanent hearing threshold shifts with subsequent evaluations finding similar associations in humans.

High-intensity underwater noise can cause permanent or temporary threshold shifts in the auditory system and, apart from being responsible for masking and behavioural changes, it is supposed to cause an increased level of stress for the animals [ 4, 10].

Without the use of coolant, the heat accumulation was much higher with the Satelec compared to the EMS device and exceeded the theoretical threshold for permanent biological damage after 10 to 15 s of continuous instrumentation (Figure 2a,c) and differed statistically significant at deltaTmax.

We have previously shown that the noise exposure used here results in a permanent shift in hearing threshold [54].
