I've reported on here a while back on the effect of a sharp tap or click supressing Hum for some seconds. A similar click can also restart it -telling me, ar least, that thresholds of 'Hum' against 'Ambient' sound in the vicinity co-exist. This is why I always stress the individual response needs first to be ascertained before any absolute values can be discussed. Without any benchmark or standard to work against- Hum will continue to perplex and annoy more than it's due.
