Sound Fact: Decibels use a logarithmic scale. An increase of 10 dB represents a perceived doubling of physical sound volume!
Decibel Noise Scaling
The decibel (dB) sound scale is logarithmic. Every 10 dB increase represents a tenfold increase in acoustic sound intensity and a approximate doubling of human-perceived loudness.
Formula Used
Relative Sound Intensity = 10 ^ (Decibel Difference / 10)
Reference Quick Chart
| Water Heater Type | Decibel Range (dB) | Human Perception Description |
|---|---|---|
| Standard Electric Tank | 0 - 5 dB | Completely Silent (No Moving Parts) |
| Standard Gas Tank | 35 - 45 dB | Soft Hum (Burner Combustion) |
| Tankless Gas (Active) | 45 - 55 dB | Moderate Fan / Gas Jet Sound |
| Hybrid Heat Pump (Active) | 48 - 58 dB | Compressor Hum (Similar to Refrigerator) |
