A receiver 26 is mounted on the part 25 either by a snap ring or by adhesive. The diameters of the tubes are arranged so as to give the same sound intensity at both ears. The receiver is connected to the amplifier by a lead 21. In a modification, Fig. 6, the receiver 26 is ...
Forward and reverse cochlear latency and its relation to the frequency tuning of the auditory filters can be assessed using tone bursts (TBs). Otoacoustic emissions (TBOAEs) estimate the cochlear roundtrip time, while auditory brainstem responses (ABRs) to the same stimuli aim at measuring the au...
large size range, and the extensive data available from domestic cats which provide a framework for relating middle-ear acoustics to structure. We report measurements of acoustic admittance in 17 live adult ears of 11 exotic species, ranging in size from sand cat (3 kg) ...
Improvements in or relating to Devices for Reducing Noises to the Ears, or Ear-plugs.4579. Atkinson, T. N. March 24. Ear instruments and hearing - appliances.-An ear plug comprises a ball or plug A mounted on a screwed shank C, which passes at an angle through an anchor-shaped plate...
Microphones having different kinds of carbon diaphragms or different sizes of granules may be used, and they may have different frequency responses as described in Specification 398,837. The hearing of the two ears may also be balanced by ear-pieces having differing outputs....
The processor may automatically determine a hearing impairment level of the user or the user may manually input the level, for both right and left ears. The user input module may allow selection of a vehicle zone for the user.
a rotatable hollow attachment J secured to the periphery of the box, which attachment is either of such a shape that it can be inserted directly into the ear, or is provided with a single or bifurcated tubular extension, the end or ends of which can be inserted into the ear or ears. ...

Directional hearing sense is due to phase and intensity differences between sounds reaching the two ears, phase differences being more effective for the lower frequencies and intensity differences for higher frequencies. As phase differences in two loud-speakers (both heard by both ears) do not ...
