High-frequency thresholds: circumaural earphone versus insert earphone.
Benefits of high-frequency audiometry in monitoring hearing sensitivity of patients administered ototoxic medications are well established. High-frequency thresholds have been reported to be variable, due in part to small differences in the placement of the earphone diaphragm over the opening of the ear canal. Reliability may be improved by using insert earphones (ER-2) when obtaining high-freq...
متن کاملE-mic: Extended Mic-stand Interface Controller
This paper describes work in progress for the development of a gestural controller interface for contemporary vocal performance and electronic processing. The paper includes a preliminary investigation of the gestures and movements of vocalists who use microphones and microphone stands. This repertoire of gestures forms the foundation of a well-practiced ‘language’ and social code for communica...
متن کامل3D conductive nanocomposite scaffold for bone tissue engineering
Bone healing can be significantly expedited by applying electrical stimuli in the injured region. Therefore, a three-dimensional (3D) ceramic conductive tissue engineering scaffold for large bone defects that can locally deliver the electrical stimuli is highly desired. In the present study, 3D conductive scaffolds were prepared by employing a biocompatible conductive polymer, ie, poly(3,4-ethy...
متن کاملInsert earphone depth and the occlusion effect.
Twenty individuals were tested to determine the occlusion effect caused by supraaural earphones and by insert earphones with shallow and deep insertion of its foam eartip. The bone-conduction oscillator was placed both on the forehead and the mastoid. It was concluded that using deeply inserted earphones is the most practical way in which to carry out clinical bone-conduction measurements.
متن کاملEffects of background noise on earphone thresholds.
Real-ear attenuation at threshold (REAT) and monaural pure-tone thresholds were determined for normally hearing adults using a supra-aural, Audiocup, and insert earphone. The thresholds were obtained in quiet and in background noises approximating the maximum permissible ambient noise levels (MPANLs) allowed in an audiometric test room specified by ANSI S3.1-1991 and OSHA (1983). The supra-aura...
