Listening difficulty and hearing aid signal processing

Not yet recruiting

• Conditions: Bilateral Sensorineural Hearing Loss

• Registration Number: CTRI/2022/11/047174
• Lead Sponsor: Mariam Elishba

Brief Summary

**AIM :**Tostudy the self-reported listening effort and working memory outcome measures ofchannelfree hearing aid.

**OBJECTIVE:**

1)Toassess the listening effort using self-reported measures using SSQ ( Speech , Spatial and Qualities of hearing scale ), and APHAB(Abbreviated Profile of hearing aid benefit )

2)To determine the sentence-final word identification and recall with noisereduction ON and OFF condition

**NEED :**

Fastersignal processing, phonemic compression and noise reduction  of channel free hearing aid should influence orinteract with the individuals cognitive process and reduce listing effort when compared multichannel signal processing technology. Hence there arises a need.

**PROCEDURE:**

Participants will be recruited from Audiology OPD after basic audiological evaluation . Participants fulfilling the inclusion criteria will undergo hearing aid trail with multichannel and channel free hearing aid. MOCA , SPIN TEST ,SWIR ,APHAB , SSQ ,RAT scale will be administered with multichannel and channel  free hearing aid with noise reduction feature on and off condition.
