dB is simply the measure of a sounds peak intensity, not it's frequency or it's duration. Sonic boom's occur at a very low frequency, between .1 - 100 Hz. Also, the duration of that noise is less since the bullet is moving away from you (sonic booms are continuous and degrade over distance). Expanding gasses from the muzzle are far more damaging since they are higher in frequency, and longer in duration. So saying that 150 db from the negates makes suppression at the muzzle somewhat pointless is false IMO. Most of the sound to bystanders and damage to your ear will be from expanding gasses. I think it's better to only be bombarded by port noise plus the sonic crack, rather than muzzle, port noise and crack.
