Influence of a flash light on the absolute threshold of hearing
TENCON 2007 - 2007 IEEE Region 10 Conference, 2007 In this study, to investigate an influence of a visual stimulus presentation on auditory sensitivity, the absolute threshold of hearing was measured under conditions with and without a flash light. In the experiment, pure tones at a frequency of 500 Hz and a duration of 0.5 s were used as the test sound for the measurement of the threshold.

The Journal of the Acoustical Society of America, 2007 This study investigated the effects of a previous sound on loudness at the absolute threshold of hearing. Change of the absolute threshold of hearing was measured when a pure tone preceded the test tone in the measurement of the threshold. The previous sound at 60 dB SPL was presented first in one ear, and then the test sound was presented in either ...

Auditory enhancement at the absolute threshold of hearing and its relationship to the Zwicker tone
Hearing Research, 1996 Auditory enhancement describes an improvement in the detection of a tonal signal in a broad-band masker with a spectral gap at the signal frequency if the signal is delayed in its onset relative to the masker. This auditory enhancement may be based on an increase of the effective signal level instead of a decline in the effective masker level. In order

Journal of Comparative and Physiological Psychology, 1975 Avoidance conditioning and the method of limits were used to measure absolute auditory thresholds, masked thresholds, and critical ratios in 4 parakeets. The same procedure was then used to study frequency difference limens in 6 additional animals. The power spectrum and "constancy of intonation" of the parakeet call were also measured and related to ...

A Time Reversal-Based Acoustic Indoor Localization System at the Absolute Threshold of Hearing
IEEE Sensors Journal, 2015 We present in this paper an acoustic indoor location system that allows a simultaneous localization of sources with different location precisions. This is achieved by the use of the time reversal technique and the code-division multiple-access operation. The system was evaluated in terms of accuracy, precision, and location delay.

Hearing Research, 2012 The ability to understand speech in quiet and in a steady noise was measured for 26 listeners with audiometric thresholds below 30 dB HL for frequencies up to 3 kHz and covering a wide range (0-80 dB HL) between 3 and 8 kHz. The stimulus components were restricted to the low (≤1.5 kHz) and middle (1-3 kHz) frequency regions, where audiometric ...

The Journal of the Acoustical Society of America, 2017 The National Park Service (NPS) has collected long-term sound level measurements from more than 800 sites, using equipment that measures 1 second, 1/3rd octave band levels. One-third octave bands approximate the critical bands for the human auditory system, and the initial motivation for collecting these data was to predict the levels at which incoming

Journal of Comparative Physiology A: Sensory, Neural, and Behavioral Physiology, 1998 Absolute thresholds and critical masking ratios were determined behaviorally for the European barn owl (Tyto alba guttata). It shows an excellent sensitivity throughout its hearing range with a minimum threshold of −14.2 dB sound pressure level at 6.3 kHz, which is similar to the sensitivity found in the American barn owl (Tyto alba pratincola) and ...
