Cuidar la audición
For decades nightclubs have been very popular around the world, in some countries are better known as discotheques or discos. The early nightclubs are dated 1840-1850 in the cities of NY and Chicago, the main concept was live jazz, swing and some other popular music genres. By the time the sound systems were very unsophisticated, it was enough to amplify the voice and instruments during the live music shows, there was not a real concern about high fidelity or acoustics.
During the 60’s there was an important change on music and sound behavior in venues, the rock music changed people demand and became important to play recorded music in the discotheques in NY and San Francisco. The most significant change occurred during the 70’s with the high-power sound system and the origin of the “modern dance clubs”. Better quality sound system appeared, more loudspeakers, amplifiers, mixers to improve sound control, later the graphic equalizers became popular, the first electronic mixers allowed better control and added more attributes to modify the music.
At the beginning of the 80’s disco music was consolidated, it demands higher standards, as an example the Studio 54 in NY which became a worldwide recognized place. More clarity in the sound, subwoofers to complement the “punch” of low frequencies, lighting systems combined with the music and the DJ became a formula for different places.
Later the electronic music arrived, the constant technological innovation step by step created higher standards. The digital era brought new tools for the DJ, samplers and synthesizers made the sound system to improve, the sound was not the same as before, the demand to reproduce different frequencies required better equipment.
The size of the sound system changed, the class D amplifiers became more efficient, que sound quality improvement was evident, lighter and compact system started replacing the traditional analog equipment.
We can keep describing more improvements and technological advancements that made the sound extraordinary, Las Vegas Sphere is an example.
Efficient equipment allows less distortion, our ears perceive more music than noise, the only problem I still can see is the high levels that we typically experience in any actual modern night club, that is the only part that we must be careful and avoid exposing ourselves to extreme high SPL during long constant period of time.
¿ Have you experienced any ear problems after being in a nightclub or concert? ¿Do you think the legislation should be stricter to avoid future potential deaf problems?
