Sound strength is measured in decibels (dB), with a normal conversation around 60 dB, a rock concert around 120 dB, and a jet engine around 140 dB. Prolonged exposure to sounds over 85 dB can damage hearing.
The enharmonic equivalent of Db is C#. Both notes have the same pitch but are spelled differently.
Noise can start to become painful at around 80-85 dB. Prolonged exposure to noise levels above 85 dB can cause hearing damage. It is important to protect your ears from prolonged exposure to high noise levels.
Sounds above 85 decibels can be harmful, especially with prolonged exposure. Sounds at or above 120 decibels can cause immediate damage to your hearing. It's important to protect your ears in loud environments to prevent hearing loss.
Sounds above 85 dB can cause hearing damage with prolonged exposure. However, sounds over 120 dB can cause immediate damage. It's important to protect your ears from loud noises to prevent hearing loss.

85 dB is bad for extended periods (8 hours). 100+dB is bad nearly instantly.
That tells it all: "Permitted Noise Exposure Time Guidelines - SPL" Sound pressure level Lp and permissible exposure time t: 115 dB = 0.46875 minutes (~30 sec) 112 dB = 0.9375 minutes (~1 min) 109 dB = 1.875 minutes (< 2 min) 106 dB = 3.75 minutes (< 4 min) 103 dB = 7.5 minutes 100 dB = 15 minutes 97 dB = 30 minutes 94 dB = 1 hour 91 dB = 2 hours 88 dB = 4 hours 85 dB = 8 hours 82 dB = 16 hours Lower dBs are said to be harmless.
You can damage your hearing. It depends also on time. "Permitted Noise Exposure Time Guidelines - SPL" Sound pressure level Lp and permissible exposure time t: 115 dB = 0.46875 minutes (~30 sec) 112 dB = 0.9375 minutes (~1 min) 109 dB = 1.875 minutes (< 2 min) 106 dB = 3.75 minutes (< 4 min) 103 dB = 7.5 minutes 100 dB = 15 minutes 97 dB = 30 minutes 94 dB = 1 hour 91 dB = 2 hours 88 dB = 4 hours 85 dB = 8 hours 82 dB = 16 hours Lower dBs are said to be harmless

Effectively, OSHA has two noise limits that apply simultaneously. First, employees may not be exposed to a full-shift (8-hour) time-weighted average noise level of 90 dB (deciBells) or more. This translates to a limit of: 90 dB averaged over an 8 hour day, or 95 dB for 4-hours as long as the rest of the day does not involve exposure to noise greater than 90 dB, or 100 dB for 2 hours, 105 dB for 1-hour, 110 dB for 30 minutes, 115 dB for 15 minutes, and no continuous noise louder than 115 dB In addition, employees who have 8-hour exposures of 85 dB or more must be placed in a Hearing Conservation Program and, in some cases must be provided with hearing protection. The table is a bit different because sounds from 80 dB and above are used in the assessment. This translates to a criterion level of: 85 dB averaged over an 8-hour day, or 90 dB for 4-hours for 4-hours as long as the rest of the day does not involve exposure to noise greater than 80 dB, or 95 dB for 2 hours, 100 dB for 1 hour, 105 dB for 30 minutes, 110 dB for 15 minutes
The enharmonic of Db is: C#
No, Db has 5 flats whilst D major has 2 Sharps.
