Intersubject variability of real-ear sound pressure level: conventional and insert earphones.
Measures of the sound pressure level (SPL) near the eardrum were determined at discrete frequencies between 500 and 4000 Hz on 50 ears using TDH-39P and ER-3A earphones with the attenuator of an audiometer fixed at 90 dB HL. Results revealed significant differences in the measured SPL between the two earphones at all test frequencies. Results also revealed large intersubject differences in the ...
متن کاملA tutorial on complex sound fields for audiometric testing.
A fundamental understanding of soundfield characteristics in enclosed spaces is required in order to appreciate and predict the behavior of complex sound fields (i.e., sound fields created with at least two uncorrelated sound sources on different axes) used in auditory tests for evaluating hearing aid performance, especially speech-in-noise tasks. This article is a tutorial starting with ideali...
متن کاملElectroacoustic calibration for sound field warble tone thresholds.
Walker, Dillon, and Byrne (1984) suggested reference equivalent threshold sound pressure levels (RETSPLs) for warble tones with specific modulation parameter values audited from a test position at the critical distance in a semireverberant sound field. This study evaluated these RETSPLs in two typical audiometric rooms and with typically encountered FM tones. Thresholds were measured under earp...
متن کاملDifferences and intersubject variability of loudness discomfort levels measured in sound pressure level and hearing level for TDH-50P and ER-3A earphones.
Loudness discomfort levels (LDLs) were measured in dB HL and SPL at discrete frequencies between 500 to 4000 Hz on 31 hearing-impaired ears using TDH-50P and ER-3A earphones. The results revealed no significant differences in the measured sound pressure level (SPL) between the two earphones at all test frequencies. However, with dB HL measurements, statistically significant differences were rev...
متن کاملAccuracy of prediction methods for impact sound pressure levels
There are various methods available for predicting impact sound pressure levels of floors. Understanding the accuracy of these prediction methods can be an important aspect of designing or refining a proposed flooring system. This paper provides a brief outline of some available prediction methods for massive (typically concrete) floors and light weight floor constructions. Consideration is giv...
