Frequency response testing apparatus, developed for use with hearing aids, comprises a generator providing a predetermined varying- frequency input for the device under test, and a discriminator which applies incremental output level signals from the device to a display matrix of LED's under the ...
To be safe, note the volume level that allows you to listen to a 1,000 Hz tone without discomfort and do not stray too far above this level, even if you can’t hear much – especially in the high range, where your hearing is the most fragile. ...
This invention primarily relates to devices for measuring the sense of hearing by free field pure tone testing. It is especially useful for the testing of infants and pre-school children; however it is not necessarily limited to such individuals. Since it is quite difficult to test the hearing...
Our B&K test rig, ready to go. We smooth our plots and calculations at 1/12th octave since this amount of smoothing removes the very fine fluctuations in the frequency response that aren't perceptible to human hearing while preserving the details that are audible to humans. For Bluetooth headp...

- Normally the audible frequency range for humans falls between 20Hz and 40000Hz, but the hearing ability can fade with age, so you can test your hearing on regular basis using our Frequency Sound Generator or Frequency Generator - Relax with binaural beats or white noise. - Remove water from...
