9 Royalty-Free Audio Tracks for "Mechanical Hum"

Just kind of a low mechanical drone.

Ambient noise outside the waiting room at edinburgh waverley station.

Loud background hum of trains idling on platform 15 of edinburgh waverley station.

Simple mechanical noise.

Just a test in a 30 by 30 room.

Low air and hum. Within a dorm room by windows. Switches back and forth between air exhalation and regular mechanical humming. Done on a tascamcrystal microphone.

Taped a pair of jrf c-series contact mics on a small, very quiet wristwatch to see if i could get a good signal. Pleasantly surprised by the result. Removed the quartz hum and de-noised in rx 7.

Tiny waves lapping the quartzite pebbles (1-2cm diameter) on a beach at lake pedder. Recorded 21 march 2019, 3am, with the internal mics on a marantz pmd661. For noise reduction, capture a noise print around 0. 09. Exceptionally quiet night, no wind, no other sounds. The gordon river power station was 20 kms distant. Other mechanical equipment or vehicles greater then 50 kms. I could just perceive the electrical hum from the station (or from transmission lines), and so could my partner, but i can’t hear it on the recording. See also "tiny waves lapping #1".

Tiny waves lapping the quartzite pebbles (1-2cm diameter) on a beach at lake pedder. Recorded 21 march 2019, 3am, with marantz pmd661 and rode nt55. Exceptionally quiet night, no wind, no other sounds. The gordon river power station was 20 kms distant. Other mechanical equipment or vehicles greater then 50 kms. I could just perceive the electrical hum from the station (or from transmission lines), and so could my partner, but i can’t hear it on the recording. At 1. 30 on the recording you can hear my partner’s soft cough coming from our tent 50m away. The crackles that sound like static come from the quartzite pebbles as they are moved around by the tiny waves. See also "tiny waves lapping #2".
