ER75 Electro-Acoustic Ear Simulator - 1

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. Portability 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. Tests 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. Automatic audiometer validation in under 5 minutes Repeatable thresholds over 0.25-8kHz Battery powered Compact, lightweight and portable Fast and efficient Instrument 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. Please note: The circumference of a headset must to sit comfortably on the ER-75 to form a seal (the unit is not considered suitable for a Pelter headset). Validation testing should be considered as an essential part of the test programme and can be required should there be an audit of the medical services. Automatic As 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.
