That's more like 30x better, since dB is log scale. Each +/- 3dB is about double/half as loud.

- Acen 8y agoIt's important to differentiate between power and perceived volume. Usually a person won't notice an increase in volume unless it has a 3-5dB (3dB = double in power) increase. And won't perceive a double in volume without a 10dB (10dB = 10x increase in power) increase and even then it depends on the specific frequency.
