Assuming this is an honest question, both the frequency profile and decibel level are dramatically different. Frequency profile is the main factor of concern. People have considerable ability to adjust to white noise, but not noise dominated by certain harmonics. I'm too lazy to look up references right now, but you can search on effects of low-frequency noise. By the way, I'm not referring to infrasound, which is frequency below the hearing threshold, and whose health effects are less well established or studied.
