Experimental: Intervention group
Participants will be included in all pre-intervention and post-assessment measures. Participants will receive the Listening Project Protocol intervention. The duration of the intervention is approximately 45 minutes per day, for 5 consecutive days.
Behavioral: Listening Project Protocol
The intervention will consist of listening to computer-altered acoustic stimulation, designed to modulate the frequency band of vocal music passed to the participant. The frequency characteristics of the acoustic stimulation are selected to emphasize the relative importance of specific frequencies in conveying the information embedded in human speech. Modulation of the acoustic energy within the frequencies of human voice, similar to an exaggerated vocal prosody, are hypothesized to recruit and modulate the neural regulation of the middle ear muscles and to functionally reduce sound hypersensitivities and improve auditory processing.
No Intervention: Assessment-only group
The assessment-only group will participate in all pre- and post-intervention assessments, but will not receive the Listening Project Protocol.
