White Noise

That mysterious hum
Is it from outer space?
Indeterminate
It’s source we cannot trace

Some say it’s what we need
A soothing calm vibration
Balm to the troubled soul
Removes all agitation

White noise apparently combines
All frequencies of sound
Blended thus emitting
‘Near-silence’ quite profound

Sometimes white noise
Signals an interruption
Connection lost, line gone dead
Zoom conference disruption

At other times this ‘absent’ sound
A very welcome aid
Its reassuring hum or hiss
Heartens those afraid

In theoretical science
And practical technology
White noise is multifunctional
Not least in space cosmology

White noise is so much more
Than something non-existent
That audible inaudible
Mystery quite persistent
