Results show that the just noticeable difference in loudness becomes greater as the overall
sound pressure level of the signal increases. On the contrary, the just noticeable difference …

In Chapter 1 it was shown why knowledge of comfort is important. This knowledge could
support the design of products such as seats, vehicles, and hand tools and increase sales …

One of the main goals of building acoustics is the prediction of airborne sound insulation
between rooms to determine the quality of sound protection. In many practical cases …

abstract Certainly people who are working in various agricultural affairs exposed to a lot of
noise sources and it has not fully specified all the risks for people who have long been …

This paper describes the results of a study aimed at developing and validating a prediction
model to assess the annoyance conditions at the operator station of compact loaders by …

Traditional noise control engineering methods are focused on reducing emitted A-weighted
sound pressure levels to meet the legislative requirements; unfortunately the reduction of the …

Cab noise characteristics of construction machines are presented. Influence of work cycles
on cab noise is studied. Cab noise generation details are analyzed. Contributions of main …

It is well-known that the reduction of noise levels is not strictly linked to the reduction of noise
annoyance. Even earthmoving machine manufacturers are facing the problem of customer …

Abstract− A new procedure for the measurement of loudness (the perceived intensity of a
sound) by persons is presented. It is based on the combination of two procedures, one …

This work aims at presenting the experience of the authors in applying the “product sound
quality” approach to the noise signals recorded at the operator station of some earth moving …
