Environment II Quiz 4
Environment II Quiz 4
Test your knowledge on sound reinforcement and environmental acoustics with our engaging quiz! This quiz comprises 10 carefully crafted questions that assess your understanding of sound control, amplification systems, and their applications in architectural design.
- Learn about sound technology and its impact on environments.
- Evaluate your comprehension of effective amplification systems.
- Challenge yourself with questions on sound characteristics and their effects.
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.
Place loudspeakers in a (BLANK) plane above the source.
Diagonol
Horizontal
Vertical
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.
Amplified spaces require much (BLANK) reverberation times and more aborbent room surfaces.
Shorter
Medium
Longer
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
