Weirdly it says "up to 10dB" attenuation.. which isn't actually that much at all. 10dB would be a halving/doubling. I'm not sure how the apparent loudness / change in waveform amplitude display is so great, considering that actual hard stat...

3 dB would be halving/doubling. With 10 dB, you would get a ratio of 10x.
