Book Description
The interior sound of vehicles is a major criterion when buying a new or used vehicle. For both pure-electric and hybrid vehicles, separately audible tonal components severely influence the pleasantness of the interior sound. Previous studies revealed that for sounds of vehicles with electrified drives, besides the tire-road and wind noise components, mainly higher-frequency tonal components influence the pleasantness. Within the present work, the audibility of those components has been determined by a modified version of an auditory masking model. For those vehicles, disturbing sound components are usually prominent during transient driving conditions. Therefore, the temporal changes of psychoacoustic parameters should be considered for the pleasantness prediction. A long short-term memory neural network depicts the relationship between time series of psychoacoustic parameters and a single value of pleasantness, which has been acquired by conducting auditory experiments with both original and augmented electric and hybrid vehicle interior sounds. The general scope of the dissertation is to develop a model of pleasantness for interior sounds of vehicles with electrified drives using a long shortterm memory model approach. The predictions form the basis for constructive countermeasures or active sound design concepts to improve the pleasantness of the interior sound.

Book Description
The noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is a critical feature for customers to assess the performance and quality of vehicles. NVH characteristics are higher among factors that customers use to judge the vehicle's quality.This book sets out to introduce the basic concepts, principles, and applications of the NVH development and refi nement of Battery Electric Vehicles (BEV), Hybrid Electric Vehicles (HEV), and Fuel Cell Electric Vehicles. Each type comes with its own set of challenges.

Book Description
This book constitutes the refereed proceedings of the 14th International Symposium on Perception, Representations, Image, Sound, Music, CMMR 2019, held in Marseille, France, in October 2019. The 46 full papers presented were selected from 105 submissions. The papers are grouped in 9 sections. The first three sections are related to music information retrieval, computational musicology and composition tools, followed by a section on notations and instruments distributed on mobile devices. The fifth section concerns auditory perception and cognition, while the three following sections are related to sound design and sonic and musical interactions. The last section contains contributions that relate to Jean-Claude Risset's research.

Book Description
Built to Love reveals how companies can create captivating products that energize the marketplace and set the standard for what customers want and expect. Firms often hope the answer is to produce the latest high technology devices - only to find that they fail to light up the marketplace. Or firms rely on ads that overstate or mislead, leaving the customer disappointed and disillusioned. Instead, a deeper emotional engagement between the customer and product is required, regardless of whether the products are physical products, services, technologies, software, systems, or brands. Using a combination of industry - based research and laboratory experiments, the authors demonstrate that customers will richly pay for products that authentically provide emotional fulfillment. They uncover the science behind successful products that create an avid and loyal following, and they present evidence that product emotions increase a product's success in the marketplace as well as a firm's success in the stock market (even when the economy is down!). A practical how - to guide, the book next shows how to analyze customers' emotional needs and translate those needs into features that galvanize customers. Throughout, the book uses revealing case studies that show how to energize customers in both consumer and business - to - business worlds, in both large and small firms.

Book Description
Since the early seventies, the development of the automobile has been characterized by a steady increase in the deploymnet of onboard electronics systems and software. This trend continues unabated and is driven by rising end-user demands and increasingly stringent environmental requirements. Today, almost every function onboard the modern vehicle is electronically controlled or monitored. The software-based implementation of vehicle functions provides for unparalleled freedoms of concept and design. However, automobile development calls for the accommodation of contrasting prerequisites – such as higher demands on safety and reliability vs. lower cost ceilings, longer product life cycles vs. shorter development times – along with growing proliferation of model variants. Automotive Software Engineering has established its position at the center of these seemingly conflicting opposites. This book provides background basics as well as numerous suggestions, rare insights, and cases in point concerning those processes, methods, and tools that contribute to the surefooted mastery of the use of electronic systems and software in the contemporary automobile.
