Noise Attenuation in Rotary Heat Exchanges
Noise attenuation in rotary heat exchangers:
Frequency (Hz) | 63 | 125 | 250 | 500 | 1000 | 2000 | 4000 | 8000 |
---|---|---|---|---|---|---|---|---|
Attenuation (dB) |
2 | 2 | 3 | 4 | 5 | 7 | 8 | 9 |
Note that larger inlet or outlet chambers should be calculated separate.
