Model 270+

Advanced two-channel diagnostic audiometer

Our most powerful two-channel diagnostic audiometer and the perfect choice for audiologists, ENTs and hearing aid suppliers within audiology.

Designed with a full range of audiological test measurements, all included in one package. Essential tests such as air conduction and bone conduction audiometry including narrowband masking can easily be performed. 

Enhanced tests such as speech audiometry (wave input or live speech) and free field testing are also part of the standard Model 270+ functionality.

All-in-one solution

Diagnostic assessment requires an audiometer that comes with no limitations. This all-in-one diagnostic audiometer can be used on a desktop as well as a portable audiometer. Combined with pure tone audiometry tests (AC, BC, masking), the device also allows recorded or live speech audiometry under headphone conditions or in free-field.

Special tests are included such as SISI (Short Increment Sensitivity Index), Stenger, ABLB (Alternate Binaural Loudness Balance) and Tone Decay. All test results can be easily stored, printed and transferred to Electronic Medical Record (EMR) systems such as ampliSuite and Noah, where further counselling tools are available.


Key features

  • Frequency range (AC): 125 - 8000Hz
  • Attenuation range (AC): -10 - 120dBHL
  • Air and bone conduction, MCL, ULL/UCL
  • Automatic AC and BC testing incl. automated masking
  • Tone selection: pure, pulsed, warble, continuous
  • Masking: narrowband (tone) or speech-weighted
  • Speech audiometry (wave file and CD input)
  • Free field assessment
  • Special tests: ABLB, Stenger, SISI, Tone Decay, HLS, MHA
  • Integrated talk forward function
  • ampliSuite software and Noah modules included.


This portable digital audiometer features all the requirements you would expect within both screening and diagnostic audiometry. Both manual and automatic (Hughson-Westlake and Bekesy) testing are available for air and bone conduction, along with helpful tools to assist so that you can determine hearing loss issues quickly and efficiently.

The Model 270+ audiometer has been designed to be ready to test with everything you require in the all-in-one package. Learn the basic operations of the Model 270+ in less than five minutes:

Full integration

Simple and efficient data management are a key requirement in offering streamlined healthcare. The Model 270+ has been designed to work seamlessly with either direct printing (stand-alone) or integrate with computer based infrastructure with included data processing and management modules included.

The PC-based ampliSuite allows for easy results download for processing and management with useful counselling tools such as speech bananas etc. Where other medical record databases are used, Amplivox includes as standard connection modules to Noah and OtoAccess®. Many other connections are available.

  • The user in focus

    Our focus is not only on providing a user-friendly diagnostic audiometer, but also considering the health of the professional. While operating the audiometer controls (level wheels and tone presentation), the user can place their hands upright for optimal hand placement. The thoughtful key layout and light ring indicators representing the selected ear side permit a constant overview of the current test situation, reducing stress and mistakes.  

    The considered design allows for complete focus on the patient with a clear display and innovative light rings to display channel rings, so that key information can be gathered with the glance of an eye.

    Focusing on a clear six button process to define test routines which allows for fast test selection, this audiometer is perfect for those new to testing and seasoned professionals alike. 

  • Clinical tests

    Special tests are common in helping to assess patient hearing issues as well as in delivering life changing solutions. The Model 270+ includes many clinical tests and counselling tools that ensure a leading patient care can be provided.

    Clinical tests include the SISI (Short Index Sensitivity Index), Stenger, ABLB ABLB (Alternate Binaural Loudness Balance) and Tone Decay Testing.

    With recorded and live speech testing, the SRT and SDT scored can easily be defined, for example at the most comfortable threshold level (MCL) for faster hearing aid fitting. Many hearing care providers favour additional counselling tools such as the Hearing Level Simulator (HLS) and Master Hearing Aid (MHA) which can be used in conjunction to help offer care that leaves the patients completely satisfied.

Masking intelligence

When to use masking in audiometric testing and at what sound level to use it is not always straightforward. The Model 270+ masking assistant informs you when masking is suggested and at the same time judges the volume of the stimulus as ideal, too loud or too soft.

This allows for exact audiometric threshold testing of air and bone conduction. When required the Model 270+ can also be set to automated testing and will apply masking levels automatically, for both air and bone conduction.
