NoopelEmergency Survival Whistle Double Tubes Safety Whistle 2 pack with keychain for Boating Outdoor Camping Hiking Hunting Sports Dog Training (2 Pack Gold)

I made a New Years resolution to stop yelling at my kids and I have broken it. I have strained my vocal chords so severely because we live in a 3 level home so I have to yell for them to hear me and I am also taking vocal lessons and don’t want to permanently ruin my singing voice by yelling so the thought of a whistle came to mind. I haven’t had to yell all day! I told the kids that two whistles means come down here and one whistle means quiet/style down. I feel so much better as a parent because now they don’t have to hear mom screaming and yelling all the time and they enjoy the whistle tactic. This was inspired by me reminiscing on basketball and cheer coaches using the whistle. I also bought a bull horn so that I can speak in a normal volume where they can hear me from 2 stories up.

I'm discussing the NOOPEL 2-pack emergency whistles.They come with lanyards, letting me wear it around my neck and under my shirt. I got the brass-colored version.Bottom line, it's small and easy to carry (or wear around your neck) and quite loud -- does what it's intended to.I'll say again, the whistle is LOUD. Be careful when using it as it'll cause temporary deafness if you're not careful! Consider sticking fingers in your ears or using ear protection when trying it out.But a loud whistle is what you want, isn't it? You want to startle intruders or call for help or maybe scare wild animals away, and this whistle should do that.I have a Decibel meter and tried blowing the whistle, holding the meter about a foot (about 30cm) from the whistle. Note that I'm wearing sound protection and I'm doing this in a closed room. The meter registered 130.5db -- and since the decibel meter can't measure sounds over 130db, it means the whistle is even louder than that.I'm happy with the purchase and recommend it to others.UPDATE: June 2020. Still using and liking, still recommend. I've found it useful when walking -- if a dog comes towards me and barks, I blow the whistle and it scares them away. There used to be 2 dogs on my walk who would run towards me and bark. Took a couple of passes blowing the whistle at them, now they see me and shy away without barking.

I used this product as a praise and worship instrument. It is just what I wanted. I will order more as people at my church where I fellowship, are now wanting that same whistle. I love love love this whistle.

These whistles are loud! Great signaler for emergency situations. No moving parts to worry about either.

Great for outdoor trips where a child might get lost. Simple device to sound in case of an emergency.
