The volume output is adjustable form the receiver and you can select from 36 different chimes. The sound output from the receiver is fairly loud and should be suitable for the average house or apartment. You could also use the doorbell in a temporary situation thanks to its easy installation and portability. Overall the wireless doorbell is pretty nice. It does exactly what it is designed to do with great range and many options for chimes.
