What are the 2 types of sound waves?
The study of sound should begin with the properties of sound waves. There are two basic types of wave, transverse and longitudinal, differentiated by the way in which the wave is propagated.
Is reverb just echo?
An echo is a single reflection of a soundwave off a distance surface. Reverberation is the reflection of sound waves created by the superposition of such echoes. A reverberation can occur when a sound wave is reflected off a nearby surface.
What is Echo Byjus?

Which are the two laws of sound reflection?

How is echo formed?
The repetition of sound caused by the reflection of sound waves is called an echo. We can hear echo when there is a time gap of 0.1 second in original sound and echo reflected sound. Echo is produced when sound reflected from a hard surface i.e. brick wall mountain etc.
Why echo is heard in an empty gym?
Sound will echo in an empty room because if there is nothing to stop the sound from reflecting between hard surfaces, such as the walls, windows, ceiling, and floor . However, the sound will continue to bounce between the hard reflective surfaces until it has lost all its energy.
What is an example of reverberation?
The definition of a reverberation is a reflection of light or sound waves, or a wide reaching impact of an action. An example of a reverberation is the sound bouncing around in a large speaker. An example of a reverberation is the impact of a no trespassing law at a shopping center on students at a nearby high school.
How long can you stay in a soundproof room?
The quietest place on earth, an anechoic chamber at Orfield Laboratories in Minnesota, is so quiet that the longest anybody has been able to bear it is 45 minutes. Inside the room it’s silent. So silent that the background noise measured is actually negative decibels, -9.4 dBA.
