The Interior Effects Room (IER) is a facility for studying human response to sonic booms experienced in an indoor environment.
Facility Characteristics
- Single room psychoacoustic facility
- Configured as a residential living room
- Controllable indoor listening environment
- Exterior sound reproduction system
- Simulates outdoor environmental noises that transmit indoors
- Two speaker arrays outside two walls

- Frequency range: 3 Hz to 5,000 Hz
- Capable of reproducing sonic booms
- Interior satellite speakers
- Simulate rattle, squeak, and creak
- Frequency range: 50 Hz to 20,000 Hz
Types of Testing
- Subjective reaction to indoor noise
- Structural response to low-frequency noise
- Applications
