Although hearing loss often affects both ears it is not uncommon that only one side is affected or that the two sides are affected to different degrees.
If hearing loss is present in one ear only, it is called single-sided hearing loss or unilateral hearing loss - or single-sided deafness (SSD) If the hearing loss is profound.
The distinction between unilateral and bilateral hearing loss is important as hearing loss in one ear can be treated differently than hearing loss that affects both ears.
CROS (and BICROS) hearing aids make use of the fact that a person with hearing loss in one ear still hears well (or better) with the other ear.
CROS stands for ‘Contralateral Routing of Signal’ and consists of two parts:
A CROS hearing aid will transmit sound and voices to let your good ear hear for both your ears. If you have good hearing in one ear and impaired hearing in the other, then a CROS hearing aid will work for you.
CROS er en forkortelse for "Contralateral Routing of Signal" (kontralateral ruting av signal) og består av to deler:
CROS II sender lyder og stemmer slik at det gode øret ditt hører for begge ørene. Hvis du hører godt på ett øre og har nedsatt hørsel på det andre, fungerer CROS II for deg.
Gjør det mulig for deg å delta i en samtale i stille og støyende omgivelser uten at du må flytte på deg.
Krever ingen kirurgiske prosedyrer. Bare slå den på og hør fra begge sider.
Så liten og diskré at du kan bruke den uten at den blir lagt merke til.
