10 Questions2 MinutesCreated by AmplifyingSound123

Check ALL Items that are TRUE How do you improve STC?

Airtight - Minimize penetrations; locate penetrations on most advantageous walls

Massive - Massive walls keep out low frequency noises

Structural Redundancy - Cavity walls, staggered stud walls

Limp, Resilient or nonrigid connection

Sound Absorbing Materials in the Cavity

Unicorn Dust

Check ALL Items that are TRUE What are some types of Electronic Sound Reinforcement?

Virtual Sound - a new innovation that allows for sound to move through waves of light emliminating the need for acoustical design

Masking Noise - "White Noise" plays over hidden speakers in open plan offices to preserve ssome of the privacy of private conversation

Loudspeakers - To amplify speech in rooms for public speech

Digital Reverberance - to enhance the extant reverberation in rooms for public music

Google Sound - an app that allows for public speakers to direct sound

Effective Amplification Systems Preserve Localization - What does this mean?

- the listener's sense that the sound they are hearing is from behind them spacially

- the listener's sense that the sound they are hearing is coming from the nearest loudspeaker.

- the listener's sense that the sound they are hearing is approaching from the original source, rather than from the nearest loudspeaker.

How do designers maintain localization when placing speakers?

For tall rooms this translates to central cluster loudspeaker groupings high above the middle of the stage 20' to 40' and slightly in front of the source. Because this sound does not come from either side, the system maintains proper localization.

The design should have two separate loudspeaker groupings, one to each side of the source, to achieve a "stereo" effect.

Where should sound techs be located in relation to the performance space?

Isolated so sound engineers can focus on what they hear in their headsets

Inside the space so sound engineers can best hear and react to the effets of the sound equipment if they are within the same space.

Backstage so sound engineers can help the cast members and evaluate sound performance

What is the HAAS Effect?

The combination of sound and frequency into a folder in your brain

The integration of first order reflections into a single fused louder image

The combination of first order reflections into a single fused folder

Brain integrates direct sounds and first reflections (those within (BLANK) for speech and (BlANK) for music) into a singel fused louder image, increasing the distictness of each note and allowing each syllable of speech to stand apart from those before and after it.

100 milliseconds for speech and 200 milliseconds for music

1000 milliseconds for speech and 2000 milliseconds for music

1 milliseconds for speech and 2 milliseconds for music

The combination of direct sounds and first reflections sounds louder and clearer to the receiver. How do designers maximize first reflections? Check all items that APPLY.

Create reflective surfaces near the source

The positions and angles of walls and ceiling segments should be shaped to encourage strong first order reflections

Sound absorbing materials should generally be placed at the far end of the room, distant from the source, to promote clarity and mitigate echoes
