Seawater - Attenuation of Sound
Attenuation of sound in seawater vs. temperature and frequency.
Attenuation of sound in seawater:
Temperature (°C) | Attenuation (dB/km) | |||||
---|---|---|---|---|---|---|
Frequency (kHz) | ||||||
0.5 | 1 | 2 | 5 | 10 | 20 | |
0 | 0.03 | 0.07 | 0.14 | 0.41 | 1.3 | 4.6 |
10 | 0.02 | 0.07 | 0.14 | 0.33 | 0.92 | 3.2 |
20 | 0.02 | 0.06 | 0.13 | 0.30 | 0.70 | 2.2 |
30 | 0.01 | 0.05 | 0.13 | 0.29 | 0.58 | 1.6 |
