The high performance and superior sound quality delivered by use of the Hearing Aid Designer is enhanced by the highly flexible and integrated system architecture of Ezairo 5900.
The Ezairo 5900 series features a 24bit precision open programmable DSP core combined with a highly reconfigurable Hear accelerator engine.
This unique dual-core architecture allows Dynamic Hearing algorithms to run with an optimal balance between performance and power consumption.
Ezairo 5900 includes all necessary on-chip peripheral blocks to directly interface with transducers, battery and controls.
As such, the Hearing Aid Designer, running on Ezairo 5900, combines extremely high performance and functionality while using battery power sparingly, thus enabling manufacturers to produce discrete, attractive and comfortable hearing aids for use in every listening situation.
"When we designed the Ezairo 5900 series, our primary focus was on performance, without compromising flexibility and power consumption", said Michel De Mey, Senior Director, Hearing and Audio Solutions at AMI Semiconductor.
"We are pleased to see that Dynamic Hearing's state-of-the-art software suite takes full advantage of our new architecture and truly demonstrates the high precision sound and computing capability of our technology".
"With Ezairo 5900's high precision sound attributes, we were able to run additional high frequency amplification to deliver natural sound to the ear", said Dr Elaine Saunders, CEO of Dynamic Hearing.
"Also, the ample available computing capability allows us to achieve higher performance from our algorithm suite and will enable manufacturers to quickly integrate our new algorithms as they become available in the future".
