with High Acoustic Power for for special industrial environments

 

General Information:
An alarming sound must have the right characteristic
tone with a good contact of penetrating harmonic
components. But for high power signalling, it is also
important that the risk of hearing damage is kept low
in case a person should come too close to the sound
source. In other words, it is a question of a balanced
tone spectrum and that is one of our secrets with the TYFON sound.

Choice of Tone Pitch:
As a choice for general purpose alarm signals, the type
MKT 75/440 can be recommended for most kinds of
noisy environment. The two dominating tone components
are 440 Hz and 880 Hz. The latter so called second
harmonic being just as strong as the basic 440 Hz, is a
guarantee for an excellent penetration.
The 370 Hz alternative has been used for decades for
air–raid warning and is also extensively used for other
types of long range public alarm (radiation, important
radio message etc.). As an alternative to 390 Hz, 440
Hz, 460 Hz and 660 Hz are recommended for special
industrial environments with intense noise of machinery
or small type MKT 75/660 is also very
good when combined with MKT 75/440 in order to give
increased distinction and detectability. The sound emitter
with the highest pitch in this family is the MKT 75/800.

 

Outdoors signalling:
The efficient range of outdoors signalling is strongly
dependent on the mounting site, preferably free and
elevated. In a normal topography with lower buildings
inefficient range 700 m for 70 dBA sound level can be
calculated in the horn direction, and prevailing, one must
calculate with considerably shorter ranges. At the same
time, the signal for good perception may be raised 70
dBA, depending on the actual find of noise.
