Conference Paper
Full-text available
The acoustic comfort of an administrative space of the University of Alicante is analyzed. Given its characteristics, the problem is limited to questions of privacy and stress since in open-plan offices, occupants are directly affected by the activities that surround them. Incorrect acoustic conditions in this type of space can cause distraction or...

Based on the results obtained in previous works, the study of the phenomenon from the point of view of the simulation in a three-dimensional model is proposed. It is verified that there is an evident parallelism between the results of the simulation and the experimental one. To delve into the question the procedure is applied in a smaller enclosure...

Conference Paper
In this paper, we propose the possibility of establishing limits for what natural reverberation are in a common room. At these limits we have called: Optimal reverberation and Saturation reverberation time. It is chosen Sabine expression for the reverberation time as the starting paradigm. From it and others assumptions like occupation of the surfa...

The acoustic critical distance in a room, represents the match distance between the direct field and the reverberated field sound pressure levels. This concept is derived from the assumption of a statistically perfect performance for the diffuse sound energy; where the level of direct sound field pressure is governed by the inverse square of the so...

The results of insulation measures carried out in accordance with ISO 717-1: 2013 and ISO 16283-1: 2014, in two rooms, are presented: one of them with a small volume, less than 50 m 3. No significant differences in the results, with fixed microphone or manual movement, are found. The question of the expansion of the frequency range for the noise in...

In this work we have studied 19 Bars-Restaurants facilities. In them, through measures "in situ", we have calculated the level of verbal interference LSIL-SIL. In order to analyze the noise situation from the point of view comfort: geometric data, reverberation and noise levels, in empty and in use room, are collected. It is also studied the arrang...

The echo phenomenon based on the definitions given in the literature of different authors will be discussed. Individual cases raised as typical risk situations echo using simple geometric tools will be analyzed by studying the set of reflections in every possible situation about the temporal (150-300 ms), and energy behavior roughly. Impulse respon...

He’s homotopy perturbation method is adapted to calculate higher-order approximate periodic solutions of conservative nonlinear oscillators for which the elastic force term is an odd nonlinear function. The method is modified by truncating the infinite series corresponding to the first-order approximate solution before introducing this solution in the...

This work comes on the comparative sound results to 'impact': for a common type of laminate floor covering mounted on several samples of "resilient support". Its sound response is analyzed in function of the subjective nuisance calculating the 'perceived noisiness' or loudness. A simple and practical device to facilitate the realization of the expe...
