Hearing Augmentation Receiver Calculator

 

 

This Calculator is to assist with the numerical requirements of receivers when provided in conjunction with a hearing augmentation system based on NCC 2022 D4D8

A hearing augmentation system is required where an inbuilt amplification system, other than the one used for the emergency warning is installed,

  • in a room in a Class 9b building; or
  • in an auditorium, conference room, meeting room or room for judicatory purposes; or
  • at any ticket office, teller’s booth, reception area or the like, where the public is screened by the service provider.

If the hearing augmentation is provided using an induction loop, it must be provided to 80% of the floor area or space served by the inbuilt amplification system.

If the hearing augmentation is provided by a system that requires the use of receivers or like, it must be available to not less than 95% of the floor area or space served by the inbuilt amplification system.

The number of speakers can be calculated by the above formula, based on the number of people that can be accommodated based on the floor area as listed under NCC D4D8 Clause 2

Further information regarding Hearing Augmentation can be found in AS 1428.5-2021, Design for access and mobility, Part 5: Communication for people who are deaf or hearing impaired.
