Answer
That depends on the sort of sound and the listener.
In hearing, the threshold of pain is the sound pressure or sound pressure level beyond which sound becomes unbearable for a human listener. This threshold varies only slightly with frequency. Our ear drums are moved only by sound pressure and not by acoustic intensity.
Different values for the threshold of pain are found in the literature:
sound pressure level in dB SPL and sound pressure in Pa.
120 dBSPL = 20 Pa
130 dBSPL = 63 Pa
134 dBSPL = 100 Pa
137.5 dBSPL = 150 Pa
140 dBSPL = 200 Pa
The volume refers to psycho-acoustic loudness. It is a common term for the amplitude of sound, the sound pressure or the sound pressure level.
Prolonged exposure to sound pressure levels in excess of the threshold of pain can cause physical damage, potentially leading to hearing impairment.

What is correct order in which to assess level of arousal?
Determine the arousal state first, using minimal stimuli and increasing intensity as needed. Start with auditory stimuli, move to tactile stimuli, and use painful stimuli as a last resort.

What intensity in dB does noise start to become painful?
It depends on the sort of noise. If you like that music you can bear it louder. 120 dB is mostly painful. Don't forget that your ear drums are moved by the sound pressure and not by the sound intensity.
Why should you start with low intensity exercise when building muscular endurance?
It is important to start with low intensity exercises to avoid muscle strain and injury. As stamina and muscles become adapted to exercise, the exercise routine can be increased.
Why is noise pollution worse on a night?
The same intensity of noise may be present both day and night, but at night people are generally trying to sleep and the noise interferes with this activity. Most noise control by-laws specify lower acceptable dB levels during normal sleeping hours, latest times for particularly noisy activities, and specific "not before" times for the start-up of noisy activities.
How do you lose weight when excersise is painful?
ease your way into exercise gently start by doing low impact exercise first, then your body will get used to it and it will become less and less painful work your way up your body will thank you for it.
