Long time asthmatic here. My portible nebulizer is over 10 years old and is coming to an end of its life. In that time nebulizers have gotten cheap (150-250 USD) in price without insurance and have changed dramatically. Ultrasonic technology and the appeal of 5 minute treatments has me very interested.

Ultrasonic toothbrushes: Which has least noise/vibration?

Which ultrasonic toothbrush has the least noise and vibration? This is for my 12-lb dog, who has a correspondingly small head. He's already great about letting me brush with a manual toothbrush, which I do nightly, but still had some periodontal pockets at his recent dental cleaning. I think I can get him to accept an ultrasonic one if I introduce it very gradually, but I want to get the gentlest one possible. Related issues inside. [more inside]

Ultra-sonic, steam or both for cleaning Antique Jewelery

I am planning to buy a jewelry cleaner for my brother-in-law who sells antique jewelry (and other antiques). Will an ultra-sonic cleaner be more useful than a steam cleaner or visa-verse. Or, does one need both to be effective?

Bad Neighbor!

Neighbor is using an ultra-high-frequency device against us at very high decibels. It causes constant low-grade nausea and a long-lasting ringing in the ears afterwards. Problem is, it can't really be heard because its such a high-frequency. Cops have come to our house, felt the nausea and ear-ringing themselves, but refuse to do anything about it because they can't "hear" it and we have no way of recording it. My question is: Can you point me towards a device that can record high decibel sound in very high frequencies so we can show objectively that this is happening? [more inside]
