Hearing Instrument Testboxes are used to verify the technical specifications of a hearing aid. These specifications may include, but are not limited to, OSPL90, harmonic distortion, frequency responses, and battery drain. ## Why Use A Hearing Instrument Test Box? Hearing Instrument Testing is vital for evaluating hearing aids, testing parameters like frequency response and distortion. This meticulous process ensures tailored, effective solutions for individuals with hearing impairment, enhancing their quality of life and communication. A Hearing Instrument Test device can also be used for RECD measurements, to facilitate REM-based fittings on infants or patients with special needs. ## Why Are Hearing Instrument Test Box Measures Important? Nearly every hearing instrument dispensed today is digital. These modern-day devices employ a variety of advanced features like noise reduction and feedback management. The Measure HIT Pro is capable of measuring and verifying these advanced features with the click of a button. In addition, the Measure HIT Pro can also be used for [RECD fittings](https://www.auditdata.com/audiology-solutions/measure/hearing-instrument-fitting/real-ear-measurement/recd-fitting/ "RECD Fitting"), using couplers. ## What Features Can Be Tested Using The Measure HIT Test Box? A myriad of tests, both manual and automated, can be performed with the Measure unit to ensure optimal performance of your patients hearing instruments. These tests include: OSPL90, Full-on Gain, AGG Input/Output, Attack/Release Time, Reference Test Gain, Frequency Response, Equivalent Input Noise, Harmonic Distortion, Battery Current, and Telecoil/Induction testing.
