Gold standard otoacoustic emissions testing

A flexible way to analyze otoacoustic emissions (OAE) responses

Madsen Capella² is so flexible that you can use it for both routine testing and more advanced cases. Multiple stimulus calibration choices and an automated frequency selection alternative are just two features that can enhance the way you work.

For stimulus calibration, we introduce Chirp or Optimized In Situ. The Chirp works well when speed is important. When combined with predefined measurement settings it is a suitable tool for general testing of patients.

When accuracy is crucial, Optimized In Situ calibration provides more confidence in your data collection. The historical probe fit and data comparison enable you to assess accurately cases where slight changes in the response are crucial, for instance, for patients receiving ototoxic medications or treatment.

An adaptable otoacoustic emissions solution

PrecisePoints^™ in Madsen Capella² provides the simplest way to set up the exact test frequencies you want. It allows the operator to quickly select commonly used audiometric test frequencies as the F2 test frequencies or set a range with predefined points per octave.

For advanced users there is the possibility to configure manually any frequency combination desired providing a virtually infinite number of points per octave.

Discover an otoacoustic emissions solution that lets you work the way you want

Intuitive easy-to-use software Madsen Capella² works with Otosuite – the proprietary software program from Natus. Otosuite is comprehensive and powerful yet easy to learn and simple to use. All of the functions you need are accessible on the intuitive control panel. It is easy to select your preferred test and measurement settings with a few clicks.
