The Doppler effect.
The Boppler effect.
The Poppler effect.
What term describes sounds capable of being heard by the human ear?
Sonics.
Wavelength.
Pranks.
Noises.
Are all sounds audible to the human ear? Why?
Yes. Because with the many advancements in robotics and radio theory allows it.
No. The average human ear cannot hear all sounds in the infrasonic and ultrasonic regions.
Maybe. It's impossible to determine if the sounds we hear are real or simply an illusion of the mind sent from our corporate overlords.
No. The average human ear cannot hear all sounds in the intrasonic and supersonic regions.
Sound waves transmitted from a source are sometimes weak when they reach the detector. What instrument is needed to boost the weak signal?
A megaphone.
A better detector.
An amplifier.
All of the above.
