ACME 828008 Siren High Volume 147

Amazon

AUTHENTIC VICTORIAN SIREN SOUND EFFECT, AN ACOUSTIC INSTRUMENT, NOT AN ELECTRONIC APPROXIMATION: The ACME 147 siren whistle produces a rising and falling siren-type sound through a precision mechanical internal mechanism, not a single tone, not an electronic reproduction, but a genuine analogue siren effect that no other currently manufactured whistle replicates. WATCHMAKER PRECISION, THE MECHANISM REQUIRES INSTRUMENT-GRADE TOLERANCES: The 147's internal siren mechanism operates at tolerances equivalent to a watch component. This level of precision is what produces the characteristic rising effect reliably and consistently, the same engineering discipline ACME applies to its professional gundog and sports whistle ranges. DESIGNED FOR THEATRE, ORCHESTRAL AND SOUND EFFECT APPLICATIONS: The 147 is used by theatre prop departments, sound designers, and orchestral percussionists who require an authentic acoustic siren effect as a period or dramatic sound element. If you need a genuine mechanical siren sound, not a recording, not a digital effect, but a real acoustic instrument in the room, the ACME 147 is the only currently manufactured option. HISTORICALLY SIGNIFICANT, ORIGINALLY USED BY VICTORIAN CYCLISTS: The siren whistle mechanism was developed in the 19th century for use by early cyclists to warn pedestrians of approach, before conventional cycle bells became standard. The 147 is a direct descendant of that original Victorian application, retaining its original mechanism and acoustic character. COLLECTOR'S PIECE FROM ACME'S HERITAGE RANGE, For whistle collectors, acoustic instrument enthusiasts, and Victorian artefact specialists, the 147 is a genuinely rare production piece from one of the world's oldest and most institutionally significant whistle manufacturers.
