I awake with a jerk, hearing a squeaking noise from the bedroom. The nose is loud and very strange. Usually, the floor only squeaks when I step on it, but never Kallua. She’s too light.

INTRODUCTION N oise is acoustically made up of numerous sound waves with anarchically distributed amplitude and phase ratios, causing an unpleasant sensation1. Noise can be continuous - when there is no variation in terms of sound pressure nor sound spectrum; floating - when it presents variations in terms of acoustic energy in function of time; or impact noise - with acoustic energy peaks lasting for less than a second, at intervals greater than one second2. Impact noises are usually produced by
