A North East manufacturer has improved its product range to help people with severe hearing problems. Rayovac in Washington has developed a longer lasting hearing aid battery that improves the performance of specialist hearing devices.
The firm has tailored the new product to meet the needs of people with cochlear implants – a device worn by the profoundly deaf and hard of hearing. The battery contains a series of technical improvements that maximises the power available to the hearing aid device for a longer period of time, improving the performance and quality of sound available to the user.
With the power demands of hearing aids worn by those with cochlear implants significantly higher than other devices, Rayovac has developed an air management system to maximise power for longer. It works by ensuring that only the precise amount of air needed to convert zinc in the battery to energy enters the cell at all times.
