Origin: Formed within English, by derivation. Etymons: self- prefix, noise n.

Etymology: < self- prefix + noise n.

†1. Apparently: egotistical writing, likened to an (unpleasant) sound. Obsolete.Apparently an isolated use.

ΚΠ

1897 M. Thompson in Independent (N.Y.) 19 Aug. 1/1 Egotism like that of Walt Whitman, which is self-noise.

2. Noise generated by a device, vehicle, etc., during operation, esp. that which interferes with the detection, reproduction, etc., of desired sounds or acoustic signals.
