Automated ABR screening

The SeraTM automated ABR screening requires minimal tester training and provides a reliable and easy to interpret pass or refer result - important in any newborn hearing screening program. SeraTM utilizes the proven CE-Chirp® stimulus which significantly reduces test time to typically less than 30 seconds. Both ears can be tested simultaneously to reduce test time, using either inserts or EarCups. Use of Earcup transducers with SeraTM helps eliminate noise in challenging testing conditions and the unique SeraTM pre-amplifier ensures optimum performance in electrically hostile environments

Unique CE-Chirp® stimulus

The trusted and proven CE-Chirp® stimulus significantly reduces your testing time and gives you more freedom to focus on your patient.

Reliable automated ABR screening

The SeraTM default automated ABR screening protocol provides a reliable result with an algorithmic sensitivity of 99.9% and a specificity greater than 96%.
