|Yes Kimberlita, wear your earplugs in most salsa clubs. And try to stay away from the speakers or the walls where sound may reflect from.
I've found that talking to the DJs does not help. I overheard one promoter instruct their DJ to turn the sound up as they could still hear people talking over the music. So, protect yourself. They won't.
The threshold of damage from noise starts at 85 decibels (dB)
Exposure to 85 dB(A) for 40 hours a week poses about the same hearing risk as being exposed to 88 dB(A) for only 20 hours, 91 dB(A) for 10 hours, 94 dB(A) for 5 hours, 97 dB(A) for 2.5 hours, and just over one hour each week at 100 dB(A).
A noisy restaurent clocks in at 85 decibels. The TTC Subway clocks in over 90 decibels. Nightclubs can be as loud as 120 decibels. The hazards to hearing double with each 3db increase.
Once your hearing is damaged, it does not come back and the damage is cumulative.
Warning signs that your hearing may be damaged include ringing or buzzing in the ears right after exposure to the noise. Sounds are muffled and it is hard to understand people talking after you leave the noisy area.
Exposure of noise has physical effects on the body:
Permanent hearing loss; Permanent tinnitus (ringing or buzzing); Stress; Increase in blood pressure, hypertension; Disturbance in rest and sleep, sleep deprivation, fatigue; Isolation or interference with activities; Absenteeism; Communication difficulties; Affected learning and education.

Have fun dancing in the clubs, but protect your hearing.
