Overview
MiNi-HAC™ Hearing Aid Compatibility Automated Test System
Hearing Aid Compatibility (HAC) evaluation of wireless handsets ensures accessibility of these technologies to the hearing impaired.
The MiNi-HAC system can be used for the design and development of wireless handsets as well as for evaluation of hearing aids used by the hearing impaired to gain access to mobile wireless technologies.
APREL MiNi-HAC™ is the commercial compliance Hearing Aid Compatibility (HAC) bench measurement system, ideal as a primary compliance instrument for Hearing Aid Compatibility or as a design/development tool for electromagnetic near-field emission evaluation of antennas and wireless devices. The system is designed for developers, compliance experts, regulators, and researchers.
APREL is a pioneer in the area of Hearing Aid Compatibility, and the MiNi-HAC™ brings APREL’s almost three decades of experience into one package. APREL is ISO 17025 accredited for HAC standards including ANSI/IEEE C63.19.
MiNi-HAC™ is an affordable and easy-to-use system for complex HAC evaluations of wireless products (handsets, smartphones, etc.). It is an expandable system which can test devices operating up to 6 GHz and which will grow with technological developments.
This product is ideally suitable for use in a fast paced development area where assessments are needed for research & development, for pre-compliance and for final product compliance testing.
