Query: Too noisy

This diffuser is easy to use and I like the all day diffusing option (since it holds more water). However, it’s noisy and sounds like constant water dripping (from the lid I assume). I often get up in the middle of the night to turn it off because of this reason. When it’s been running a while and the water level is lower, it gets louder.
