Blast overpressure induced structural and functional changes in the auditory system.
Blast overpressure of sufficient intensity can produce injury to various organ systems. Unprotected ears result in the auditory system being the most susceptible. The injuries to the auditory systemExpand

The quantitative relation between sensory cell loss and hearing thresholds
On the basis of experimental data obtained from 420 noise-exposed animals (chinchilla), the amount of sensory cell loss has been quantitatively related to the amount of permanent threshold shift atExpand

The effect of impulse intensity and the number of impulses on hearing and cochlear pathology in the chinchilla.
Forty-one chinchillas, divided into seven groups, were exposed to 1, 10, or 100 noise impulses (one every 3s) having peak intensities of 131, 135, 139, or 147 dB. Hearing thresholds were measured inExpand

Discrimination of transient signals having identical energy spectra.
Pairs of waveforms having identical energy spectra were generated using a technique developed by Huffman [IRE Trans. IT8, S10–S16 (1962)]. A pair of such waveforms differ only in their phase spectra.Expand

Relations among early postexposure noise-induced threshold shifts and permanent threshold shifts in the chinchilla.
Threshold shifts (TS) were measured at various times following a wide variety of noise exposures on over 900 chinchillas. An analysis of postexposure TS measures and noise-induced permanent thresholdExpand

Threshold recovery functions following impulse noise trauma
An analysis of the pure-tone threshold recovery functions obtained from 118 chinchillas exposed to high-level impulse noise showed that there are at least three distinctly different types of recoveryExpand

Additivity of Forward and Backward Masking as a Function of Signal Frequency
Temporal masking of tones by clicks was investigated using a forward‐masking paradigm, a backward‐masking paradigm, and a combined backward and forward paradigm. The amount of temporal masking wasExpand

An isohazard function for impulse noise
Existing criteria for safe exposure to impulse noise do not consider the frequency spectrum of an impulse as a variable in the evaluation of the hazards to the auditory system. This study wasExpand

A Health Hazard Assessment for Blast Overpressure Exposures Subtitle - Use of Animal Test Data in the Development of a Human Auditory Hazard Criterion for Impulse Noise (Part 1)
An energy trading rule of 10 log N or 6 log10 N; where N is the number of impulses, best organized the data for N between 10 and 100. Expand

Temporary Threshold Shifts Produced by High Intensity Freefield Impulse Noise in Humans Wearing Hearing Protection
Abstract : Exposure to high intensity impulse noise produced by modern military weapons is known to be hazardous to hearing. Hearing protection is required; however, there is no generally acceptedExpand
