From a psychological standpoint, noise can disturb human mental performance in the
workplace. While loudness and sharpness of noise are usable factors for evaluating the …

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 …

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 …

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 …

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 …

This paper describes the use of a multi-objective optimisation code aimed at identifying
solutions which improve the sound quality at the operator station of earth moving machinery …

The development of fluid power systems for use in agricultural and construction machinery
faced in the last years a substantial contribution due to the increasing role played by …

Numerical simulation is widely used in product design for different purposes ranging from
structural modelling, FEM analysis, vibroacoustics to multi-objective design optimisation …

The term “Mobile Machine” refers to off-road machines primarily used for earth moving,
construction and road maintenance works. The mobile machines are all included in the …
