Acme Authentic British Police Whistle by Metropolitan

If you need to command attention indoors or outdoors without being too annoying, the Acme Metropolitan British Police Whistle (Model 15) is perfect for that. Produces two different tones which combine to make a third “beat” tone, sometimes referred to as a “heterodyne”. The whistle is tuned to make a very distinctive, pleasant sound, unlike most common whistles. Great for getting the attention of noisy children indoors or out. Doesn’t make ears ring afterwards. Easy to articulate multiple or coded bursts with tongue. I haven’t tested for such but probably can be heard long distances outdoors because it sounds different than common noises. Attached is a video I made with a recording of the exact whistle I received, to hear how it sounds.

Excelente silbato

Nice weight/quality whistle. As whistles go, it also has a nice tone and is loud enough to call my dog from a good distance away. I never trained her to come to a whistle, she just does. It is certainly loud enough to use as an emergency alarm as well.

Acheté pour ma fille de 12 ans qui va à l'école en bus comme sifflet de détresse. Bel objet mais pas assez puissant, je l'ai renvoyé.

Auqneu no es exactamente como lo esperaba, (esperaba un dorado y con un sonido diferente), no tiene sonido tan agudo como los silbatos nacionales y esta bonito en plata.
