Information on hearing loss

March 14th, 2013 Posted in OMNITRONIC, worth knowing Tags: , ,

More and more young people suffer from hearing loss of 25 decibel or more, mainly caused by loud music from portable MP3 and CD players or discotheques.

Everybody operating amplification systems should know to what sound pressure levels he exposes his or the audience’s hearing. As an average levels between 75 and 105 dB(A) in the discotheque or 95 and 115 dB(A) at a rock concert are reached. Individual peaks can exceed the pain level at 130 dB(A). Such levels are typical for motor chainsaws or jack hammers.

Overview on subwoofer types

subwoofer

The human ear is mainly adapted to the frequency range where speech is transmitted. Frequencies below this frequency range are less noted although the same physical level is present. In practice, this effect requires higher bass power e. g. by more powerful subwoofers, more subs or a mixture of both. As speakers generally have a low efficiency comparable to a halogen lamp, manufacturers try to achieve the highest efficiency by optimized housing shapes. But not every housing shape is suitable for every event location and audience. The following article should help to find the suitable subwoofer type.

1. Introduction

The loudspeaker celebrates its 150th anniversary based on the invention of the telephone by Philipp Reis in the year 1861. Already in the year 1878, the electro-dynamic loudspeaker was patented. This kind of loudspeaker is still built into most speaker-systems today.

If such a loudspeaker is operated without housing, an acoustic short-circuit is produced because the sound waves produced by both membrane sides are eliminated by each other. The volume is clearly reduced, especially the lower frequencies. A pragmatic use is not possible like this so that diverse types of loudspeaker housings for different applications were developed.
