(((•))) Kockum Sorties with Valve Unit TV 784 A high-power whistle according to IMO for vessels of 200m or more in length To make your voice heard - thaf s the task of your ship's whistle. How to do it is the business The use of sound signals for attention and information in the most efficient way is not so simple from ail aspects. That is the reason behind the regulations determined through the 'International Convention for Preventing Collisions at Sea, 1972'. Nowadays, each vessel trom 12 metres and more (length over all) must be equipped with sound signal appliances which are type approved according to the IMO regulations. Hence, one part oí the responsibility is the manufac- turer's, but still one important part is the shipowner's - the choice of appropriate equipment for the The radiated sound output is represented by its Sound Pressure Level and is measured in dB. For the purpose of the IMO regulations, the demand on radiated sound is defined by the 1 /3 octave Sound Pressure Level measured at (or recalculated to) 1 metre distance from the horn mouth and measured within the frequency range 180-700 Hz, where the hearing mechanism has a high sensitivity. The reason behind the stipulated use of 1/3 octave band filters when measuring is connected to the theory of the hearing senso. A 'T^mplex1' sound like that from TYFON or SUPERTYFON consists of several harmonic components. Consequently, the total SPL value is con- siderably higher than the measured (stipulated) 1/3 octave value. The ability of sound signal to be heard above noise when reaching a distant vessel is highly dependent on the presence of components which are sufficiently strong in the so-called sound spectrum. A ship's whistle of trade mark TYFON of SUPERTYFON always has a favourable spectrum and a high total SPL value. The broad spectrum gives 'signal efficiency' and a Combined systems - installation advice For full information regarding 'Combined Systems' and IMO installation regulations etc., see our leaflet IMO Valve Unit The Valve unit TV 784 has a good air flow section, thermostatic heating, exchangeable choke flanges and filters. The apparatus is fitted with two coils for normal and emcrtjoriry opo-albn and lanyard as standard. (See separate leaflet).
