Silencer and muffler design is primarily accomplished via cut-and-try approaches in many industries. Noise issues are identified close to production and mufflers are designed and tested. In this workshop, a design process for mufflers is recommended. The steps that may be taken during the 1) clarification of task, 2) conceptual design, 3) detailed design, and 4) prototyping phases are outlined, and the process is demonstrated at each step for a cross-flow type muffler. It is shown that plane wave analysis is especially valuable in the conceptual design stage whereas numerical simulation is of greater value in the detailed design stage. Basics and tips for both plane wave analysis and numerical simulation are discussed. Measurement of transmission loss using the two-load method will be described and demonstrated using a transmission loss test bench.

The purpose and orientation are to empower engineers to recognize and fully connect their innate hearing capabilities with interactive analytic tools to characterize, design and improve mobility-product sounds considering human perception. An overview differentiates sound quality engineering from general acoustics as historically practiced, introduces the scientific field of Soundscaping, and provides a thought-context for productive work. “Ear training” examples will be included for recognizing sound characteristics such as modulation, tonality not caused by pure tones, and various types, scales and superpositions of time-dependence. The workshop illustrates and trains the approach to issues by linking perception with technical measurements, including both conventional and psychoacoustic tools. As always, a CD of the presentation will be given out at the close of the Workshop.

An important trend among vehicle NVH engineers is to produce the attractive engine sounds matching with a vehicle concept and engine performance. Recently customers have much more interests in their personal preferences and enjoying tuning their cars. The PESS(Personalized Engine Sound System) has been developed for making a unique and individual concept of a vehicle. The system helps customers make variety of engine sound in a single vehicle using active sound design technology. In this system, three different concept of engine sound has been defined-Dynamic, Sporty, and Extreme. Each of the engine sounds can be adjusted with a parameter that determines the timbre such as main orders, half orders, and high orders. In addition, the extent to the drivers stepping on the accelerator pedal has been used as a parameter to differ the sound response. An AVN application has been implemented that allows users to easily design those functions.

How to decrease noise and vibration exposure has been of interest for many years. Empirical data have verified that too high dose values can create multiple problems to a human body - often severe. Some years back, the European Machinery Directive has increased the responsibility for manufacturers and employers to make sure limits are complying with legislation. Classical technology often consists of passive solutions aiming at trying to cut back on noise and vibration levels. For low frequency, these methods are often lacking the needed performance especially if weight should be considered at the same time. A smart combination of passive and active techniques can make a real difference. Today, with possibilities for low cost and embedded electronics and the rapid development of new actuators, a vast range of applications are possible for this combined combat approach, with a financial advantage as well.

The accumulated damage that a product experiences in the field due to the variety of vibration stresses placed upon it will eventually cause failures in the product. The failure modes resulting from these dynamic stresses can be replicated in the laboratory and correlated to end use environment to validate target reliability requirements. This presentation will discuss which random profile is needed to simulate end use environment, how to combine multiple vibration environments into one, and how to use FDS to accelerate the test.

Title: Study on Active Noise Control of Blower in Fuel Cell Vehicle under Transient Conditions Authors: Zuo Shuguang, Zhang Jun, Wu Xudong, Hu Jiajie, Long Guo Abstract: Blower is one of the main noise sources of fuel cell vehicle. In this paper, a narrowband active noise control (ANC) model is established based on adaptive notch filter (ANF) to control the medium-high frequency noise produced by the blower. In actual application, the frequency of reference signal differs from the frequency of the noise signal inevitably. This difference is referred to as frequency mismatch (FM) which greatly degenerates the performance of the narrowband ANC algorithm. Under transient conditions, in order to reduce the FM of ANC for blower, a new Frequency Mismatch Filtered-Error Least Mean Square algorithm (FM-FELMS) is proposed to attenuate blower noise.
