### Match the following acoustic phenomena with their descriptions:

Echo = Sound waves reflected with sufficient magnitude and time delay Long-Delayed Reflection = Similar to echo with a somewhat less time delay Flutter Echo = Rapid succession of small echoes between parallel reflective surfaces Sound Concentration = Reflections from concave surfaces concentrating in hot spots

### Match the following acoustic phenomena with their descriptions:

Coupled Spaces = Two adjacent rooms with at least one highly reverberant space Distortion = Undesirable change in musical sound quality due to uneven absorption Room Resonance = Certain frequencies sounding louder than others within a narrow band Sound Shadow = Area not receiving adequate direct and reflected sound

### Match the following acoustic phenomena with their descriptions:

Whispering Gallery = High frequency sounds creeping along large concave surfaces Sound Concentration = Concentration of sound reflections in hot spots at the expense of dead spots Distortion = Uneven and excessive sound absorption causing undesirable change in sound quality Room Resonance = Certain frequencies sounding louder than others within a narrow band

### Match the following acoustic phenomena with their descriptions:

Flutter Echo = Rapid succession of small echoes observed between parallel reflective surfaces Sound Shadow = Area not receiving an adequate amount of direct and reflected sound Coupled Spaces = Two rooms adjacent to each other with at least one highly reverberant space Whispering Gallery = High frequency sounds creeping along large concave surfaces

## Study Notes

### Acoustic Phenomena Matching

• Acoustic phenomena need to be matched with their corresponding descriptions
• The matching process involves identifying the correct description for each acoustic phenomenon
• No specific acoustic phenomena or descriptions are provided in the given text
• Further information is required to complete the matching process
