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).
You can measure the sound pressure with a sound pressure level (SPL) meter. Loudness ist a psycho acoustical sensation.
For frequency ranges, we can hear from 20 Hz to 20000 Hz (20 kHz). This is due to a limit on the length of our cochlear basalar membrane. If it were longer, we may be able to hear a greater range. For loudness, using a standard pressure level (SPL) absolute value system, we can hear at soft as 20 dB SPL (just audible whisper) to about 120-140 dB SPL (which will begin to cause hearing loss and irreversible 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.
