Research Subject Information

Study Purpose: Hearing aids are not able to completely restore hearing to normal.  Often, speech is difficult to understand, especially in noise.  The aim of this research is to investigate a novel sound processing strategy for hearing aids to see how it can be used to improve the way individuals with hearing loss understand speech.


Who can participate:  We are looking for hard-of-hearing individuals who are 18 years or older who either wear a hearing aid or have been told they need one. 


What to Expect:  A hearing test will first be conducted to determine the amount of hearing loss in each ear.  The hearing test and the subsequent study tasks will be performed in a sound-treated booth.  During these we will ask you to listen to a series of speech sounds and then respond using a computer mouse.


Experiment sessions are generally scheduled for one or two-hour periods.  We have allotted time for breaks and encourage you to take them when you feel they are necessary.


Location and Parking:

Our new location has convenient, free parking!  Click here for Google Map


The Experimental Amplification Research (EAR) Lab is located on the third floor of Lyles-Porter Hall (LYLE on the map) on the Purdue University campus.  LYLE is located at the corner of Harrison St and University St.


Participants can park in the designated spots for the “SLHS Clinics” in the Harrison Street Garage (PGH on the map) and then walk directly into LYLE.


Once inside LYLE, proceed to the main elevators and stairway.  Please wait in the seating area near the elevators on the third floor and someone will greet you there.
