Sure, and 10db means "10x more power". But:

1. 10x more power than what? It changes, and you Just Have to Know.

2. It's 10x more power; so if you're measuring power, like pascals, then 10db means 10x more pascals. But if you're measuring something like voltage, then it's not 10x more voltage, it's something else.

3. And if you're talking about sound, you may be talking about objective power; or you might be talking about how much more powerful it seems to humans.

That gives me an idea - explicitly state the basis and multiply. So the current notation "3 dBm" should instead be "1 mW × 3 dB".

Furthermore, any addition in the logarithmic domain must be grouped, like: "3 dBm + 5 dB" --> "1 mW × (3 dB + 5 dB)".
