There are several discussions about devices that can monitor the sound level and alert you if the level goes beyon your set criteria. Use search terms such as sound monitoring Another benefit of having that capability is being able to prove the sound level was acceptable if you have a neighbor complaint. Not sure how to monitor smoking in real time, however.
