what type of sound does it make?

like an air horn on a boat, extremely loud, extremely effective against people, cars, dogs, etc.

It's almost similar to a truck horn. It's loud, between a motorcycle / car (with electrical horn) and a truck.

White noise is one of several choices for sound. It turns on with a simple combination on/off and volume knob. It stays on until turned off.

It sounds very similar. I would compare it to the type of sounds a xylophone makes, where a stick is hitting bars at different tones.

No it doesn't. We have a sound machine and the peep is specific to sudden noises or louder noises than what the sound machine produces.

Is it the level indicator? (The rolling ball thingy) That might make a noise.

There are several different sounds to choose from, e.g. rain forest, waterfall, pure white noise which sounds like static, rainfall, waves, etc. I am using the running stream. The sounds quality is about like those sound machines on baby stuff, but it does the trick for our dog.

I've never heard it make a sound and I use it pretty regularly in the summer time when my asthma is acting up. Hope that helps!

It does not unfortunately. But it's many settings allow for some crazy sustain and distort options. Awesome sounds!

I would say it makes an average vacuum cleaner noise. It does not have a really high (or whiny timbre) I do not currently have any pets...so I can't say for sure.

It makes a faint sound, more like "thud, thud, thud". I have one on my desk and it's audible. But I barely notice it.

It makes normal mouse sounds. But if you're looking to open it up to dampen the sound, this uses the square/cubic switches which you can't silence.

It makes a whoosh sound. About twice as loud as a PC. It's not annoying, very even sound.

It depends on how loud the volume is... but some external sounds are heard.

I bought it as a gift for my niece, so I don't really remember. But I think it may make noise.
