PSYCH 2H03 Lecture Notes - Lecture 8: Stapedius Muscle, Hair Cell, Amusia
Document Summary
Pitch is related to frequency of sound high frequency = high pitch. When different sounds combine, they produce timbre. We can"t amplify every sound otherwise sometimes it would be too loud. We have a stapedius muscle which tightens when the amplitude is high to limit the amount of amplification. The more noise you hear today the less noise you"ll hear tomorrow" you can damage hair cells permanently and they won"t work as well the next day. Mozart effect: people who listened to music before doing a task were better at performing spatial reasoning tasks for 15 minutes but after that, they had no advantage, therefore, not that much support for mozart effect. Social cohesion: if you are making music in a group, you are forced to work together and this is beneficial because of shelter, catching food, etc. Those creatures participating in music can live longer as a result.
