Several of Sonic’s BTE, miniBTE, and miniRIC hearing instrument lines have received IP57 certification
for dust protection and water resistance.
Specifically, BTE, miniBTE, and miniRIC hearing instruments in the Bliss, Flip, Pep, ion, Touch, and 
Sonic’s protective features include water repellant membranes over microphone inlets, rubber seals on battery compartments, and Sonic’s hydrophobic coating. Together, these protections demonstrated a high degree of water resistance and dust protection in the IP57 tests.
“IP57 certification further validates the value of the protective measures taken in the construction of all Sonic hearing solutions,” said Kathy Landon, Sonic vice president of branding and professional services.
The IP Code or Ingress Protection Rating classifies and rates the degree of protection provided against intrusion of solid objects (dust) and water in mechanical casings with electrical enclosures. IP ratings are made up of two digits, representing protection levels for dust and water. This means that for the Sonic products certified as IP57, dust will not penetrate in a quantity sufficient to interfere with satisfactory and safe operation of the hearing instrument and that the instruments will work normally after a temporary immersion in water.
“The entrance of water is not totally prevented, however, and end users should not wear Sonic instruments while swimming, snorkeling, or diving as they are not designated for these kinds of activities,” explains Joseph Ranasinghe, sonic director of operations.
Ranasinghe advises that if users accidentally drop their instruments in water or get them very wet after being worn uncovered in the rain, water should be gently wiped from the outside of the hearing instrument, the battery removed, and water in the battery door wiped off. End users should allow the instrument to dry with the battery door open for approximately 30 minutes, then insert a fresh battery and close the battery door. The instrument should work normally again.
