Acoustic Flashcards
is a science which deals with the production, control, transmission, reception and effects of sound in an enclosed space.
Acoustics
is the human ears response to pressure fluctuations in the air caused by vibrating objects.
Sound
What are the 3 types Nature of sound?
- Speech
- Music
- Noise
the number of sound ripples generated in unit time.
Frequency
What are the 4 Physical Quantities of Sound?
- Frequency
- Speed
- Wavelength
- Intensity
What are the two characteristics of Sound?
- Loudness
- Pitch
What is the Acoustical Concerns in Architecture?
Noise Control
What are the 5 Principal Acoustical Defects of Rooms
a. Prolonged Reverberation
b. Echo
c. Resonance
d. Undue Focusing of Sound
e. Flutter Echo
Is defined as the amount of sound power falling on (or passing through, or crossing) a unit area.
Intensity
is a measure of the intensity of sound and is expressed in decibels (dB)
Loudness
is the frequency of sound wave perceived by the human ear.
Pitch
the control of air- borne noise through the insulation of sound or the shutting-out of unwanted sounds from the outside.
Noise Control
long reverberation time(RT) due to large amounts of highly reflective surfaces and/or to large volume of space which will take considerable time for reflected sound to die out.
Prolonged Reverberation
distinct reflection of original sound which results when the path of reflected sound is 20m (65 ft) or more than the path of direct sound.
Echo
is the reinforcement of certain sound frequencies due to sympathetic vibrations.
Resonance
