SPL stands for Sound Pressure Level, and 86 dB represents the loudness of the sound in decibels. An SPL of 86 dB is approximately equivalent to the noise level of heavy traffic or a vacuum cleaner from a few feet away. It is considered moderately loud and prolonged exposure may cause hearing damage.
dB IL refers to decibels of insertion loss, which measures the reduction in sound intensity caused by an acoustic barrier or material. dB SPL refers to decibels of sound pressure level, which measures the intensity of sound relative to a reference pressure level. In cases where insertion loss is measured as a reduction in SPL (e.g., soundproofing materials), dB IL can be equivalent to dB SPL.
To convert from dB HL (Hearing Level) to dB SPL (Sound Pressure Level), you typically need the specific audiogram for the individual. Once you have the individual's threshold values at different frequencies, you can use them to make the conversion. Each audiometric frequency has a specific conversion factor to convert from dB HL to dB SPL. It is not a direct and consistent conversion across all frequencies.
Is there a problem? Reference sound pressure po = 20 µPa = 2×10^−5 Pa (Threshold of hearing). Reference sound pressure level Lpo = 0 dB-SPL (Threshold of hearing level). Get sound pressure p when entering sound pressure level Lp = 92 decibel (dB). Sound pressure p = po×10^(Lp/20) Pa (= N/m²) = 2×10^−5×10^(92/20) Pa = 0.796 Pa.
About 20 dB SPL (sound pressure level).
A sound level of 86 dB is considered quite loud and can be compared to heavy traffic noise or a blender. Prolonged exposure to sounds at this level can lead to hearing damage.
dB HL stands for decibel Hearing Level, and dB SPL stands for decibel Sound Pressure Level.
dB IL refers to decibels of insertion loss, which measures the reduction in sound intensity caused by an acoustic barrier or material. dB SPL refers to decibels of sound pressure level, which measures the intensity of sound relative to a reference pressure level.

It depends on how loud it is. 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. Different values for the threshold of pain are found in the literature: Here are some sound pressure levels SPL in dB and the sound pressure in pascals of the sensed possible threshold of pain: SPL 120 dB = 20 Pa SPL 130 dB = 63 Pa SPL 134 dB =100 Pa SPL 137.5 dB =150 Pa SPL 140 dB =200 Pa
The usual soundlevel can be between 0 dB SPL = 20 µPa (threshold of hearing) up to 130 dB SPL (threshold of pain). An average sound level could be at 85 dB SPL. Scroll down to related links and look at "Average sound pressure levels".
There are several types of dB. dB SPL are decibels measuring sound pressure levels. There is an accepted reference point of 0 dB SPL which equals 20 micropascals = 2 × 10-5 pascals. dB SL are decibels measuring a signal relative to an individuals auditory threshold. For example, if a person's minimum threshold is 30 dB HL (yet another type of decibel measuring how much worse a person's hearing is based on a referential dB level) and a signal is at 40 dB HL, the sensation level of this signal to this individual is 10 db SL (40 dB - 30 dB = 10 dB SL).
If you mean the sound pressure level that causes pain, it is about 120 dB SPL.
130 dB is an SPL commonly considered to be the threshold of pain. Between 120 and 140. http://ccrma-www.stanford.edu/~jos/st/DB_SPL.html
60 dB sound pressure level is about conversational speech listened in 1 meter distance.
A 10 dB sound pressure level (SPL) is 0.000063 pascal and 100 dB is 2 pascal. Loudness is a problematic psycho acoustic feeling. I don't know what three times louder really means.
