Sera™
Newborn hearing screening made efficient
Early intervention in newborns with hearing loss is vital to ensure normal development of the child’s speech, language and social competencies. With a powerful combination of the automated auditory brainstem response (ABRIS), distortion product OAE (DPOAE), and transient evoked OAE (TEOAE) hearing tests, Sera™ offers early detection of hearing loss, making it the perfect choice for any newborn hearing screening program. The intuitive workflow and the large touchscreen make Sera™ fast and easy to operate.
Automated ABR screening
The Sera™ with ABRIS (automated ABR) provides a reliable and easy solution to interpret pass or refer result – important in any newborn hearing screening program.
Based on knowledge
The Sera™ automated ABR solution builds on extensive clinical research and our many years of experience in ABR testing.
Unique CE-Chirp® stimulus
The trusted and proven CE-Chirp® stimulus significantly reduces your testing time to typically less than 30 seconds* and gives you more freedom to focus on your patient.
Optimized for noisy environments
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.
Simultaneously test both ears
By using either insert phones or EarCups you can test both ears simultaneously and reduce your test time.
“ The intuitive workflow and the large touchscreen make Sera™ fast and easy to operate when testing newborns, even with minimal training. "

Reliable automated ABR
The Sera™ default automated ABR protocol provides a reliable result with an algorithmic sensitivity of more than 99.9%.
Sera™ ABRIS
OAE screening in seconds
Sera™ offers fast DPOAE and TEOAE screening of newborn babies in an easy to use, handheld device. Place the probe in the baby’s ear and a few seconds later clear test results will be displayed.
Designed with care for small ears
Both the SnapPROBE™ for Sera™ as well as the eartips are specifically designed to fit into an infant’s ears. Stability of the probe in the ear during measurement is improved, and the filters that protect the transducer against debris are very easy to replace.
Less noise ensures reliable results
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.

SnapPROBE™
A small and lightweight probe for the tiniest of ear canals
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.
SnapPROBE™ is a small and lightweight probe with a smooth surface. The smooth surface means it is easy to keep clean, accommodating for the hygienic demands in clinical practice.
SnapPROBE™ comes with two designated ear tips of a conical or narrow shape, which are longer compared to other models. They are designed to catch earwax and other foreign bodies that could harm the probe electronics.
Combined with its designated ear tips, SnapPROBE™ increases stimulus stability and reduces noise during measurements.
Automated ABR and DPOAE and TEOAE screening
A powerful combination of screening protocols
It has never been easier
The Sera™ menu and interface are quick and easy to use. All main assessment functions are accessible from the touch-enabled 'home' screen.
You are ready to begin testing after just three button presses and it has never been easier or faster to enter new patient information. The device displays the transducers and electrode locations for all hearing test types once you have chosen or entered your patient. This ensures consistent and accurate preparation of your patient – every time.
Newborn hearing screening
Early identification of hearing loss is vital to ensure normal development of a child’s speech, language and social competencies. With a powerful combination of ABRIS1, DPOAE and TEOAE, SeraTM offers the opportunity to easily and quickly detect a potential hearing loss in newborns, making it the perfect choice for any hearing screening program.
1. The ABRIS module offers automated ABR testing
Results in no time
Following the simple on-screen instructions, you can complete your automated ABR screening in less than 30 seconds. You can also complete OAE screening in a few seconds.
Designed for use
Sera™ fits comfortably into your hand and with its bumper case and touch-enabled overlay screen, it is well protected from knocks and bumps during every day use.
Wireless
Sera™ comes with a wireless charging cradle ensuring that it is always ready for testing when you are. Test data can be printed wirelessly using the HM-E200 printer. The printer features an OLED display to help navigate the menu and has a long battery life up to 14 hours in standby mode.
Sera™ made mobile
The Sera™ Transport Cart offers great mobility and ease of use. It stores the equipment in an organized way and lowers the risk of contamination by keeping the equipment away from the patient.
Features
- Five wheels for great mobility
- Handle that makes it easy to maneuver
- Retainers for equipment and accessories
- Integrated storage bin for waste
- Storing bracket for Sera™
