3.1.2 CSP Speculations in Sound

What is sound measured in according to the text?

• Hertz
• Decibels (dB)
• Wavelengths
• Frequencies

Which of the following best describes how sound works?

• It only travels in one direction from the source
• It requires no medium to transfer
• It transfers through electromagnetic waves
• It transfers as an acoustic wave through a medium

What are the three distinct phases of sound communication?

• Absorption, reflection, transmission
• Generation, transfer, reception
• Input, processing, output

Which sensor channel is best for approximating how humans hear?

• A-weighted
• B-weighted
• C-weighted
• D-weighted

At what decibel level does sound become potentially harmful with prolonged exposure?

• 75 dB
• 80 dB
• 85 dB
• 90 dB

What component inside the human ear is similar to the diaphragm in a sound sensor?

• Cochlea
• Eardrum
• Auditory nerve
• Hair cells

What is the recommended maximum duration for safe exposure to sounds below 85 decibels?

• 4 hours
• 6 hours
• 8 hours
• 12 hours

Which part of the ear contains fluid-filled, spiral-shaped bone?

• Eardrum
• Cochlea
• Auditory canal
• Middle ear

What happens when sound waves reach the eardrum?

• They are converted to electrical signals
• They cause vibrations
• They are amplified
• They are filtered

How long can temporary hearing loss last after intense sound exposure?

• 4-8 hours
• 8-12 hours
• 12-24 hours
• 16-48 hours
