Filter Speech Filter Essay
Filtered Speech Experiment
Purpose
The purpose of the filtered speech experiment was to look for three things. The first was to see/hear which frequencies can be eliminated from speech signal and conversely which frequencies can not in order to understand speech. The second purpose was to learn more about sound filters; and the third was to understand what it is like to experience hearing loss.
Instrumentation
The instruments we used during this experiment were:
1) Low pass filter of the Coulbourn insrument
2) Tape recorder
3) Tape of two syllable words
4) Speaker (non-human)
Methodology
The experimenter selected an initial cut-off frequency of 1000 Hz on the low pass filter, and then reduced the frequency by 1000 Hz increments.
