Audiocups permit accurate pure tone audiometry in conditions of ambient noise too high for unshielded earphones and can be easily fitted to any audiometer headset using standard TDH 39 or TDH 49 earphones.
• Complete freedom from threshold shift- no change in audiometer calibration at the time of fitting
• Subsequent periodic recalibration can be affected on standard ISO 6cc coupler without the removal of inserts from Audiocups
• Invaluable where a silent cabin or soundproof room is not available
• Give extra attenuation when a booth is available
