Audio Room Acoustics Equations:
From: | To: |
Reverb Time (RT60) is the time required for sound to decay by 60 decibels in a room, while Delay Time represents the time it takes for sound to travel a specific distance. These parameters are crucial for audio room acoustics design and analysis.
The calculator uses the following equations:
Where:
Explanation: The RT60 equation calculates reverberation time based on room volume and absorption, while the delay equation calculates sound travel time over distance.
Details: Accurate acoustic calculations are essential for designing recording studios, concert halls, theaters, and any space where sound quality matters. Proper RT60 ensures optimal sound clarity and intelligibility.
Tips: Enter room volume in cubic meters, total absorption in sabins, and distance in meters. All values must be positive numbers for accurate calculations.
Q1: What is a typical RT60 value for different rooms?
A: Recording studios: 0.2-0.5s, concert halls: 1.5-2.5s, classrooms: 0.4-0.6s, churches: 2.0-4.0s depending on size and purpose.
Q2: How do I calculate total absorption (A)?
A: Total absorption is the sum of absorption coefficients multiplied by surface areas for all materials in the room.
Q3: Does temperature affect sound speed?
A: Yes, sound speed increases with temperature. The calculator uses 343 m/s for standard room temperature (20°C).
Q4: What factors affect RT60 accuracy?
A: Room geometry, furniture, audience presence, humidity, and temperature can all affect actual RT60 measurements.
Q5: When is delay calculation important?
A: Delay calculations are crucial for speaker placement, sound system design, and ensuring proper timing in multi-speaker setups.
