Reference equivalent threshold levels for pure tones and 1/3-oct noise bands: insert earphone and TDH-49 earphone.
Reference equivalent threshold sound pressure levels (RETSPLs) were determined for 20 subjects for pure tones and 1/3-oct noise bands. Two transducers were used: a Telephonics TDH-49 earphone mounted in an MX-41/AR cushion, and a Danavox SMW insert earphone coupled to an "HA-2" earmold. RETSPLs for pure tones transduced by the TDH-49 earphone were very similar to those published previously. For...
متن کاملReference threshold levels for an ER-3A insert earphone.
The purpose of this study was to obtain normal hearing thresholds for an ER-3A insert earphone as a contribution for future standardization and for comparison with previous studies and interim ANSI and ISO insert earphone reference equivalent threshold sound pressure levels (RETSPLs). Hearing thresholds were obtained on each ear of 48 normal-hearing subjects from 125 to 8000 Hz using ER-3A and ...
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...
متن کاملSound Pressure Levels in 2 Veterinary Intensive Care Units
BACKGROUND Intensive care units (ICUs) in human hospitals are consistently noisy environments with sound levels sufficient to substantially decrease sleep quality. Sound levels in veterinary ICUs have not been studied previously, but environmental sound has been shown to alter activity in healthy dogs. HYPOTHESIS Veterinary ICUs, like those in human medicine, will exceed international guideli...
متن کاملInfant sleep machines and hazardous sound pressure levels.
BACKGROUND AND OBJECTIVE Infant "sleep machines" (ISMs) produce ambient noise or noise to mask other sounds in an infant's room with the goal of increasing uninterrupted sleep. We suggest that the consistent use of these devices raises concerns for increasing an infant's risk of noise-induced hearing loss. We therefore sought to determine the maximum output levels of these sleep machines. MET...
