Eligibility

Inclusion criteria

Inclusion criteria: 1 Individuals who can speak and comprehend English 2 Individuals of either gender 3 Individuals with B/L normal hearing sensitivity ( 4 Normal middle ear function

Exclusion criteria

Exclusion criteria: 1 Individuals having co-morbid conditions like intellectual deficit, central auditory processing disorders that may hinder understanding and realization of the proposed tasks. 2 Those who are having speech identification scores less than 90%.

Design outcomes

Primary

MeasureTime frame
Baseline speech identification scores (SIS) will be obtained and comparison and correlation will be carried out with the scores obtained after implementing the varying depths of frequency modulation. Comparison and correlation will be done after converting the raw scores into percentage scores. Timepoint: 8 months

Secondary

MeasureTime frame
1 Effectiveness of TKEO based filter method in extracting varying depths of frequency modulation 2 The effectiveness of the method in extracting the speech signals from the competing speech signal 3 Identification of speech in presence of noise based on the TKEO based filter Timepoint: 8 months
