Well you won't be listening to the ticking of the clock that's for certain!
My Carrera is 1976 and at highway speeds conversation is possible but with voices raised.
But hey, the car sounds glorious. The flat six engine sounds as good as a V8, (without the slurping appetite for fuel.) You buy a Carrera for excitement, right? Quiet, it aint.

http://www.utexas.edu/research/ctr/research/articles/nvh.html Noise levels are variable per the institution doing the testing , but if you look at Consumers Reports individual car reports you'll get a good comparison.
The decibel noise level of a concrete breaker is at around 111 to 113. This can vary depending on what concrete breaker one is using, and might have a different noise level.
The noise of a fan can be measured in decibels using a sound pressure level meter. Knowing the level of noise allows people to classify as pollution or conducive.
Yes, it's not how to reduce roots blower noise level, it's how to reduce turbo blower noise level. Normally turbo blower noise level is less than 80 dba when roots blower noise level is more than 90 dba, some user are still not satisfied, they want the noise level below 60 dba or even 50 dba. Turbo blower ZCJSD has it's own suggestion to reduct turbo blower noise level: Wrap the outlet pipe with sound-absorbent material, please see below photo:
This sounds like the AOS - air oil separator.

Sound level is measured in decibels (dB) using a sound level meter. Sound becomes noise when it is unwanted or excessive, typically around 85 dB for prolonged exposure or 120 dB for instant damage. Noise can also be subjective, as what is considered noise can vary from person to person.

Check the level of the power steering fluid. A low level or no level of fluid will cause the groaning noise.
Decibels.
high noise level and low sensitivity
