Abstract

The obligatory evoked cortical potential measurement mainly used to check maturation of the brain structure. The advancement of digital technology made possible to fit hearing aids even severe loses. Improved SNR, directional microphone other feature made hearing aids uses popular among children. The selection and fitment procedure of optimum level of hearing aids mainly relay on parental feedback. Therefore present study aimed to find out the relationship between behaviour speech perception ability and objective measure of cortical evoked P1 peak. 87 hearing aids users were recruited in the study with mean age of 8.61 years and SD 1.62 years. Intelligent Hearing System 3.36 Smart Evoked Potential clinical instrument was used for recording free field evoked potential. Hindi Speech perception test was used to measure speech perception skill. Results indicated that children with good speech perception showed significant inverse relationship with latency of P1 peak. This study discussed use of P1 peaks latency to measure speech perception ability and auditory cortex maturation and functionality.
