GROUP11 Flashcards
the science concerned with the production, control, transmission, reception, and effects of sound
Acoustics
subdiscipline of acoustics that explores the relationship between people and sound throughout history
Archaeoacoustics
the study of the production, transmission, and reception of animal sounds in nature.
Bioacoustics
the subdiscipline of acoustics that deals with the conversion of electrical signals into sound waves and vice versa
Electroacoustics
is a numerical rating of how well a building partition, such as a wall, floor, or ceiling, Blocks airborne sound.
Sound Transmission Class (STC)
STC Rating which classified as the threshold at which privacy begins
STC rating of 45
the study of the propagation of sound in water and the interaction of the mechanical waves that constitute sound with the water, its contents and its boundaries.
Underwater Acoustics
is the science and engineering of achieving good sound within a building . It focuses on designing spaces to control unwanted noise and create an acoustical environment that is suitable for its intended purpose.
Architectural Acoustics
What is the relationship between loudness and amplitude?
Loudness is directly proportional to amplitude.
At what decibel level does sound become physically painful to humans?
130 dB
Which frequency range can the human ear typically hear?
20 Hz to 20,000 Hz
What does a wavelength represent in a sound wave?
The distance between two consecutive peaks of the wave
Why is effective acoustical design important in spaces like classrooms and conference rooms?
It ensures sound transmission is clear and improves speech intelligibility
Which statement best describes the purpose of acoustic control systems in a space?
To optimize sound quality, reduce noise, and improve communication.
Which of the following is not a benefit of well-designed acoustics?
Improving internet speed
