Absolute threshold of hearing decreased by perceiving a previous sound
Acoustical Science and Technology, 2007 In the present study, we investigated the effect of a previous sound on loudness at the absolute threshold of hearing. The change in the absolute threshold of hearing was measured when a pure tone preceded the test tone for the measurement of the threshold.

Absolute Threshold, Noise-Induced Hearing Loss, and Cochlear Pathology in the Chinchilla [PDF]
The Journal of the Acoustical Society of America, 1974 Absolute thresholds were determined in the chinchilla using a new behavioral procedure. The animal was reinforced with a 45-mg pellet (Noyes) for depressing and holding a key 1–7 sec and either releasing it during a 2-sec tone presentation or not releasing it during a 2-sec catch trial.

Frequency-dependent changes in absolute hearing threshold caused by perception of a previous sound [PDF]
The Journal of the Acoustical Society of America, 2007 This study investigated effects of a previous sound presentation at the absolute threshold of hearing. Changes in threshold were measured when a pure tone at 60dB SPL preceded a test tone in the contra- or ipsilateral ear. When the previous and test sounds both had the same frequency of 500Hz, threshold decreased approximately 2dB in the contralateral ...

Changes in absolute hearing threshold depending on sound pressure level of a previous sound
Acoustical Science and Technology, 2008 In this study, changes of the absolute threshold of hearing were measured by presenting a previous sound in the contralateral or ipsilateral ear. The sound pressure level (SPL) of a previous sound was 40, 60, or 80 dB to investigate the dependence of the threshold change on the SPL of a previous sound.

Perceptual Consequences of “Hidden” Hearing Loss [PDF]
Trends in Hearing, 2014 Dramatic results from recent animal experiments show that noise exposure can cause a selective loss of high-threshold auditory nerve fibers without affecting absolute sensitivity permanently.

Hearing in the starling (Sturnus vulgaris): Absolute thresholds and critical ratios [PDF]
Bulletin of the Psychonomic Society, 1986 Operant conditioning and a psychophysical tracking procedure were used to measure auditory thresholds for pure tones in quiet and in noise for a European starling. The audibility curve for the starling is similar to the auditory sensitivity reported earlier for this species using a heart-rate conditioning procedure.

Absolute Thresholds for Hearing Measured by Small Earphone and Acoustic Gains of Hearing Aid
AUDIOLOGY JAPAN, 1972 The absolute thresholds for hearing were measured by small earphone which was calibrated in 2cc coupler in 16 deaf children with and without hearing aids. And the differences of these values at each frequency were compared with the gains of the hearing aid.Theoretically the differences must be corresponded with the gain of the aid, but practically they

Auditory and cognitive performance in elderly musicians and nonmusicians. [PDF]
PLoS ONE, 2017 Musicians represent a model for examining brain and behavioral plasticity in terms of cognitive and auditory profile, but few studies have investigated whether elderly musicians have better auditory and cognitive abilities than nonmusicians.

The effects of industrial noise of higher spectrum on the workers’ auditory perception abilities [PDF]
Vojnosanitetski Pregled, 2016 Background/Aim. Results of previous studies gave support to the idea that machines in power plants produce noise of different levels of loudness and frequency, and that it could cause deterioration of the hearing ability of workers.
