Much louder than any bell. When I removed it from the box I did not think it was going to do the job. Sure enough, I plugged it in and the ring was louder than I could have expected. Great coverage for the warehouse.

Installed one of these in our noisy warehouse. Just plugs into a standard telephone line and is adjustable. Now we can hear when the phone is ringing, thank you.
