Touch Design Moisture Resistance
 
 

Moisture Resistance

Today’s hearing aid wearers aren’t sitting around on the couch. They’re outdoors, they’re active, and they’re counting on products that can stand up to heat, humidity, and sweat-prone environments. Sonic Touch delivers with a product design that offers unprecedented moisture resistance. Every element of Sonic Touch has been carefully constructed to keep moisture out and to preserve the integrity of its delicate electrical components.



 
Tested to a Higher Standard

The ASTM B117-03 standard, originally created for use in the automotive industry, helps determine potential device failure from metal corrosion. When hearing devices are subjected to these tests, they are placed in a 97° F environment with very dense atomized fog created from 5% salt water solution.
Sonic Touch and nine other commercially available receiver-in-the-ear style products were tested under this condition until an audible failure was detected. A higher score in these ASTM B117-03 test results is better.
