Lecture 1: The Nature of Sound and Psychoacoustics Flashcards
What is the nature of sound?
weq
What is the speed of sound? What are the different equations? What are the components?
wdq
What is the wavelength?
sda
What is the speed of sound in air at room temperature?
sad
What property changes the speed?
ads
How is wavelength dependant on frequency?
dwasf
What is the relevance of wavelength for spatial hearing?
sadsg
How is sound localised using the wavelength?
asdd
How does background noise affect speech recognition?
asdsf
What is a spectrogram? What does it show? What are the properties?
asdaf
What are the important quantities on a spectrogram?
asdaf
What is intensity? Define.
fsg
How much the intensity increased to make it seem like a 4x increased in loudness?
asfg
What is loudness?
afg
What is the decibel scale?
DGGHR
What is the number of a phon of a sound?
sfg
What is a sound with a negative phon? What is a sound with a positive phon? What is the sound with a 0 phon?
egsva
What is the hearing threshold?
faghg
What are the different sound ranges on a decibel scale?
fasgg
What is range of sounds that the humans can hear in the decibel scale of loudness?
afsgg
What is the human frequency range?
faasfg
What are the frequencies most used? Why? Where is the human ear most sensitive to?
asfggf
What needs to happen at higher frequencies?
sadf
What frequencies does hearing loss first happen?
