| h English (en) | Ship's whistles must be very loud for safety on the seas. Modern ship's whistles can be electrically or steam driven. The RMS Queen Mary was originally equipped with three electric ''Tyfon'' whistles in 1932. They could be heard at least ten miles away and were tuned to 55 Hz, a low bass ''A'' note that was chosen for maximum passenger comfort despite the high sound pressure level. One of the three whistles was taken back to Kockum Sonics in Malmö, Sweden, where it was refurbished for a new life of service aboard the RMS ''Queen Mary 2''. Modern IMO regulations specify ships' whistle frequencies to be in the range 70-200 Hz for vessels that are over 200 meters in length. Traditionally, the lower the frequency, the larger the ship. The ''Queen Mary 2'', being 345 meters long, was given the lowest possible frequency (70 Hz) for her regulation whistles which means she carries both 70 Hz modern whistles and a single vintage 55 Hz whistle. |
