Pello Audiology Instrumentation


Is the GSI Pello portable?

Yes, the Pello is small and lightweight, making it ideal for any environment, regardless of testing space size. The Pello's portability makes it a great option for use at offsite testing or satellite offices.

How is the Pello adaptable to my clinic’s needs?

The Pello comes with a standard configuration that includes air, bone, and speech testing. However, as your clinic's needs change, you can easily upgrade your device at any time to include the Speech Plus, Special Tests, or High Frequency licenses. This makes the Pello a perfect tool to grow with your practice.

Does the Pello come with word lists built into the device?

Yes, the Pello comes with more than 100 common word lists that may be organized into a “favorites” list for each test type. You can seamlessly implement the reliability and consistency of recorded speech stimuli without fumbling with external devices during a patient exam.

Is there a way to switch between mastoid bone and forehead testing?

Both calibrations are stored to address various bone conduction audiometry needs. Audiologists can switch between forehead and mastoid bone testing as dictated by the patient/test environment.

What are some of the benefits for the configurable tests and preferences?

You can maximize your workflow and speed of testing when using the configurations and preferences. You may choose to start in the speech screen rather than the tone screen, the left ear rather than the right, a specific dB level, and frequency based on user or facility preferences.

Audiologist Testing Patient Hearing

The Pello has four testing modules that can be used to customize the diagnostic audiometer. The standard configuration includes air, bone, and speech audiometry. The Speech Plus package adds Quick SIN BKB-SIN and AZ Bio tests that are used for cochlear implant evaluations. The Special Tests option includes test types that can bring additional insight into an audiometric evaluation. This includes the TEN test to identify cochlear dead regions and the ability to control the instrument with an external keyboard for efficiency. Finally, the High Frequency option adds on high frequency testing to the audiometer that is ideal for many scenarios, including ototoxic monitoring.
