Electro-acoustic ear simulator
The ER-75 electro-acoustic ear simulator is the perfect solution for performing objective validation of audiometers and audiometric equipment, ensuring optimum performance when testing for hearing loss.
At only 500g (1.1lbs), battery powered and with a lightweight and compact design, the ER-75 can be used for both static and mobile requirements.
Fast and efficientInstrument validation can be completed in under 5 minutes, allowing users to identify if the audiometric facility (audiometer, booth, headset and all associated cables) are performing in an accurate manner. Any changes to the measurements can then be identified by comparing with previous results and remedial actions can be taken to ensure test accuracy.TestingTests provide repeatable thresholds over the frequency range of 0.25kHz to 8kHz, thereby simulating the patient response and enabling the user to identify hearing loss issues. This ensures compliance at all hearing test frequencies used in an actual hearing assessment.
AutomaticAs the simulator is completely automatic, validations are carried out using standard and Audiocup configured audiometry headphones (connected to the audiometer), which are placed over the ER-75’s built-in microphones.
