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

Bonus Question: If constructive 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 is Destructive interference?
The canceling interference occurs when two waves occupy the same space at the same time and disturb the medium in opposite ways so that the disturbance is smaller than the disturbance of either wave separately.

These locations on the side walls are often treated first to reduce mid-frequency reflections.
First Reflection Pints

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

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

You decide the question.
What is it called when it takes time for a sound source to decay to 60dB from its original source?
This common microphone problem occurs when vibrations or footsteps create unwanted low-frequency sounds in a recording.
A. RT60
B. Handling noise or vibration noise

What is the issue here?
Flutter Echo

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

Which is a common solution to mid-frequency issues?
Bass traps or Acoustic Paneling

Bonus Question: What is the Haas Effect?
OR
What are the 3 types of diffusers?
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.
Manhattan, Skyline, Spektrum D20/Wood

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.

Comb Filtering occurs due to in_ _ _ _ _ _ _ _ _ _ between a direct source and its ref_ _ _ _ _ _ _ _. These ref_ _ _ _ _ _ _ _ _ can cause time delays because the path from the direct source (speaker) to the listener's ear is shorter than that of the ref_ _ _ _ _ _ _ to the ear.
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.

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.

EQ is an abbreviation of the word e___________. Think of EQ as a m____ for f__________ or a means to b______ and e____ out f__________ on individual tracks or in context within a mix. It is used to f__ sound p_______ as well as s_____ or creatively change a sound's t___
EQ is an abbreviation of the word equalisation. Think of EQ as a mixer for frequencies or a means to balance and equal out frequencies on individual tracks or in context within a mix. It is used to fix sound problems as well as shape or creatively change a sound's tone

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.
500
When sound waves from multiple drivers travel different distances and create areas of cancellation and reinforcement, the result is this phenomenon.
What is Acoustic Lobing?
500
This issue causes certain frequencies to become weaker when direct and reflected sound waves arrive out of phase.
Phase Cancellation

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

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