The Vertex Aerators are some of the most quiet on the market, but they do hum. The statistics show that Vertex Aerators run around 60 decibels but what does that mean? Well, its about the same loudness as normal conversation, but people don’t hum often so that is not very helpful.
Here is a great way to find out for yourself just how loud 60 decibels would be if you have a Droid phone. My husband just showed me this App and it is so cool and its free. It’s called ‘Sound Meter’ and the ‘lite ‘ version is a free download. Just download this cool app and then walk around household appliances and you will get to sample what runs around 60 decibels. Try it on your heat pump, they are usually just a little noisier than a Vertex.
