singing
A cat will make a hissing sound when it feels that it is in any form of danger. This sound is made to warn other animals or people off.
The sound you hear when you hold a seashell to your ear is actually the ambient noise around you resonating within the shell's hollow structure. It's not the sound of the ocean itself.
they can hear sound in ears
Sound perspective is the way you hear a sound. (Where you hear it coming from)
Air itself does not produce sound, but sound travels through the air as a medium. When an object vibrates, it creates sound waves that travel through the air until they reach our ears, allowing us to hear the sound.
Not everyone will hear the trumpet sound.
"Hear" doesn't have an "a" sound at all; it has a long "e" sound.
When you're playing with a headset plugged in to your amp, those around you can hear the acoustic guitar itself, but not the sound coming out of the amp, as the headset cancels the sound from coming out the speaker.
Yes, ear hairs help to protect the ear canal and enhance the ability to hear by capturing and directing sound waves towards the eardrum.
There is no where for the sound wave to reflect
This is a rather general question, but the reason for this is because the car is travelling slower then the speed of sound, and so the sound of the engine and the wheels against the surface travels faster then the car itself, hence why you will hear it before the actual entity reaches you.
