What is Direct Sound?
Sound is captured by our ears or a microphone when the source is close enough tothe mic/ears.

Bonus Question: What is Constructive Interference?
Enhancing interference occurs when two waves occupy the same space at the same time and disturb the medium in the same way so that the disturbance is larger than the disturbance of either wave separately.

What are the 3 types of Sound Treatment?
Diffusion, Absortion, Reflection

True or False: It's okay to have a few parallel walls in my acoustically treated room.
False

What is Compression?
is the increase of a medium’s density.

Is this used for Diffusion, Absorption, or Reflection?
Reflection

Bonus Question: What is the Haas Effect?
The Haas effect occurs when a listener experiences two sounds—often copies of one another—that are separated by a sufficiently short time as a single sound event.

Bonus Question: How is Constructive interference different from Destructive Interference?
Constructive interference requires waves to be in phase, while destructive interference requires them to be out of phase.

What is Comb Filtering? Or give me an example of it.
Occurs due to interference between a direct source and its reflections. These reflections can cause time delays because the path from the direct source (speaker) to the listener’s ear is shorter than that of the reflection to the ear.

Can this be used as Diffusion, Absorption, or Reflection?
Absorption

Bonus Question: What's a good height for a small studio/home studio?
8 ft.

What is Rarefaction?
Rarefaction: is the decrease of a medium’s density.

What is Room Mode?
Frequency whose wavelength coincides with the dimensions of a room.

Can this be used as Diffusion, Reflection, or Absorption?
Diffusion

True or False: Sound waves lose energy as they travel
True. That way it makes it harder for it to bounce off of two parallel panels.
500
What is Reverberation?
Multiple, random reflections occurring too close together in time to be heard separately.

What was wrong with the Beyoncé So-Fi Stadium concert, acoustically speaking?
Sound bounced against the roof and walls, creating a tinny and echoey experience

True or False: A Velocity Trap needs to be PLACED on a surface to slow down sound waves.
False
