A PC-based audiometer to empower your clinic

Clinical audiometer with dedicated test modalities

Madsen Astera2 gives you new possibilities to help more patients. Use it as a pediatric audiometer. Perform a tinnitus evaluation. Or do both! No matter what your specialty, Madsen Astera2 delivers the tools you need for audiometry excellence. Explore the possibilities of:

  • Fully integrated tinnitus questionnaires (THI, THS, TFI,) enable you to store, review and share data during assessment
  • Psychoacoustical tests like pitch and loudness matching, Minimum Masking Level (MML), and Residual Inhibition (RI)
  • Special tests such as TEN test and SAL test

Flexible audiometer helps you focus on your patients

Flexible and easy to use, you can operate Madsen Astera2 in three different ways: via the optional control panel, a mouse/keyboard connected to a PC, or directly on a touch screen – depending on your needs and clinical set-up.

New Sunshine control panel with large friendly icons enables you to switch from a classical view to a touch screen making daily routine tasks, such as an audiometer test even easier.

Discover what a PC based audiometer and Otosuite software can do for you

Madsen Astera² drives efficiency throughout your clinic. At its core is Otosuite software that integrates everything you do into one system. You can transition seamlessly from audiometry to video otoscopy, clinical OAEs, tympanometry and PMM. Store, share and report all data in the Otosuite software universe or integrate directly with Noah and Electronic Medical Records (EMR). New software updates on a frequent basis mean your audiometer is always up to date. Expand with new audiometer test modalities when you need them, and access new features for existing test modalities as they become available.
