Abstract
An interface adapted for use with an audiometer, including a digital wireless interface supported by a base unit and a remote unit wherein the base unit receives signals from the audiometer and provides the signals to the remote unit via the digital wireless interface.
Claims20
An interface adapted for use with an audiometer, comprising:
- a digital wireless interface supported by a base unit and a remote unit wherein the base unit receives signals comprising test sound information corresponding to a test sound from the audiometer and provides the signals as digitally encoded test sound information corresponding the test sound to the remote unit via the digital wireless interface,
- wherein the digital wireless interface provides at least 120 decibels of dynamic range bandwidth.
A method for calibrating an audiometric testing system to a test subject, the audiometric testing system having a digital wireless interface, the method comprising:
- producing a test sound by insert earphones coupled to a sound level meter, the producing using the digital wireless interface to transmit the test sound as digitally encoded test sound information corresponding to the test sound;
- monitoring a corresponding sound pressure level;
- and
- adjusting the audiometric testing system via the digital wireless interface to match the sound pressure level to a predetermined value;
- producing the test sound in an ear canal of a test subject;
- determining a deviation between a reference equivalent sound pressure level (RESPL) of an ear and a standard RESPL;
- and
- adjusting the audiometric testing system corresponding to the deviation.
5 more elements
An interface for providing an appropriate dynamic range for audiometric testing comprising:
- a digital wireless interface supported by a base unit and a remote unit wherein the base unit receives a signal comprising test sound information corresponding a test sound from an audiometer and provides the signal as digitally encoded test sound information corresponding to the test sound to the remote unit via the digital wireless interface, wherein an amplitude of the signal provided via the wireless interface is automatically scaled based on a comparison of an average amplitude of the signal to preset thresholds,
- wherein the audiometer is further configured to provide a masking signal for a non-test ear.
