Newborn hearing screening made efficient
The Sera™ automated ABR algorithm uses weighted averaging technology to combat against noise in the recording. Using the EarCups with Sera™ also helps to reduce noise in challenging testing conditions.
The unique Sera™ pre-amplifier ensures optimum performance in electrically hostile environments.
A group of dedicated engineers at Interacoustics have perfected the OAE detection algorithms, offering unprecedented reliability in their resistance to noise and other artifacts.
Together with its sleek design and special on-screen user guidance, Sera™ makes sure that you always obtain a proper probe seal.
CE-Chirp® 200 Hz – 11 kHz Level: 35 dB nHL Analysis time: 3 minutes
2000 to 5000 Hz Level: L1 = 65 dB SPL, L2 = 55 dB SPL Analysis time: 60 seconds
1500 to 4000 Hz Level: 83 dB peSPL, peak to peak calibrated, AGC controlled Analysis time: 60 seconds
Newborn hearing screening requires complex and sensitive technology to be able to record the electrophysiological and physiological responses (ABR and OAE). At the same time, newborns have very small ear canals, which means the probe must be quite small and lightweight to fit properly. In addition, newborns often have earwax and fetal fat in their ear canal, which can impede the sensitive equipment.
