The Harp Plus audiometer offers a wide range of tests, including pure tone audiometry, logoaudiometry, and special tests such as ABLB, SISI, Stenger, DLI, and tonal decay.

Features:
- Versatility: Performs air, bone, and vocal audiometries, standard audiometries, including pure tones and speech, automated Hughson-Westlake tests, ABLB, SISI, Stenger, DLI, Tonal Decay, 2-channel Master Hearing Aid.
- Color screen: It has a 4.3" TFT LCD graphic screen that displays the full audiogram during the exam.
- Connectivity: It easily integrates with NOAH and Maestro software through a USB connection, without the need for additional drivers.

Advanced functionalities:
- 2-channel master hearing aid. It allows the evaluation of hearing aids.
- Automated audiometry. Includes the Hughson-Westlake method for automatic threshold tests.
- Masking. Offers options for narrow band noise (NBN), white noise (WN), and speech noise (SN).

The Harp Plus combines high-level features with ease of use and portability, making it ideal for a wide range of professionals, from hearing aid dispensers to audiologists in clinics and hospitals. Its compact dimensions (32 x 32 x 9 cm) and light weight (1.8 kg without printer) make it easily transportable.
