Speech Perception Study with Low-Pass Filtering

This study is looking at how low-pass filtering speech affects how well people understand speech. Low-pass filtering speech means removing some of the higher-pitched sounds from speech. Researchers want to see if this change in sound affects your ability to recognize or locate speech. You might be able to join if you are a native speaker of American English, between 19 and 50 years old, and have normal hearing (250-8000 Hz). The study is looking for 480 participants. The main goal is to measure your speech recognition or localization score on Day 1. The current recruitment status is unclear.
