“…11 A disk horn manufactured by FIAMM is considered and the effect of the mechanical characteristics of the mounting bracket is taken into account. It is worth noticing that the important effect of the mounting bracket has been highlighted in Kang et al 10 as well. The paper is organized as follows.…”

“…In Bonfiglio and Pompoli 9 a finite element method was adopted to optimize the geometry of the snail horn, in order to increase emitted sound pressure. The quality of sound generated not only outside the vehicle, but also inside was studied in Kang et al 10 and an optimal horn was designed by means of transfer path analysis and boundary element analysis.…”

Usually cars are equipped with disk horns. In these devices electromagnetic energy is converted into mechanical energy of two nuclei that vibrate and impact each other-the impacts excite the disk that radiates sound. This paper aims at understanding the results of acoustic tests carried out on horns with different excitation voltages and different mounting brackets. Since many non-linear phenomena are inherent in the vibrations of the nuclei, a detailed model of the electromechanical system is developed. Results show the dependence of operating frequency on the input voltage and the role played by the various mechanical and electrical parameters on the dynamics of the horn. Particular nonlinear effects, like sub-harmonic excitation, are presented and discussed. A general agreement between experimental results and numerical simulations is found.

“…Yan and Jiang 6 suggested a procedure which determined the contributions of sound sources to each sound quality attribute, for analyzing sound quality contribution of panel radiation noise of the vehicle by applying an operational path analysis (OPA) method combined with partial singular value decomposition (PSVD) analysis and introducing the sound quality objective assessment. Kang et al 7 describe the design method of a dual-shell car horn (DSCH) with good interior sound quality based on the boundary element method and transfer path analysis (TPA) using a prediction model of the perceived sound quality to determine the two fundamental frequencies of the DSCH. Wang et al 8 proposed a hybrid approach called FEM-ANN model by combining the finite element method (FEM) and artificial neural network (ANN) to predict the acoustic behavior of an auditory system, which could simulate the acoustic behavior of an auditory system and help in revealing the mechanism of human auditory perception.…”

Correlational studies of order noise sample tuning and subjective evaluation test of sound quality were conducted to achieve sporty sound quality and confirm the correlation between the auditory sense (subjective) and the order noise level (objective) of vehicle exhaust noise under acceleration. First, the frequency range and the order ingredient of sporty quality noise were confirmed by a study of ear-hearing subjective feeling on the basis of physiological acoustics. By using an order tuning software that was developed independently, the second, fourth, and sixth order noise A-weighting sound pressure level (dB(A)) of the exhaust noise of an objective vehicle were tuned segmentally into numerous sound samples. Furthermore, samples with high sporty sound quality were selected through subjective evaluation, and the A-weighting sound pressure level (dB(A)) distributions of the second, fourth, and sixth order noise of these samples were analyzed. Consequently, the relative size relations of the second, fourth, and sixth order noise of all the exhaust noise with sporty sound quality were determined. In addition, the curve distribution zones of the corresponding order noise were formed and the order quantitative target of the sporty sound quality was considered. Finally, four passenger vehicles with representative sound qualities (sporty, quiet, and characterless) on the market were selected as the benchmark vehicles; their order noise was objectively tested and their sound qualities subjectively evaluated. Meanwhile, the order noise objective test result was compared with the order target. Results showed that when the fourth and sixth order noise curves relative to the second order noise curves were within the order target zones at most of the engine speeds, the exhaust noise of the vehicle had considerable sporty sound quality; otherwise, it did not have such a sound. Therefore, the order target of the sporty sound quality was accurate and effective.
