— this paper outlines a number of steps for human-computer interaction design using sound as representation-auditory icons. The design process is based on listening tests, gathering free-text identification responses from participants. These responses and their classifications can then suggest how accurately the sounds can be identified and possible metaphors and mappings of sound to human acti...

Vehicle noise emissions are an ongoing research topic in the field of sound quality design. Another area, which been hardly investigated in the past years, is the warning function of this noise for other road users, especially pedestrians. Therefore, this paper will show results of experiments dealing with the detection of the sounds of different cars in a typical urban background noise. Moreov...

Acoustical parameters of porous materials give the necessary and important information for noise control engineers. Profound knowledge their physical characteristics enable an effective sound absorber material design. The theory of sound-absorbing materials has progressed considerably during the last decade. A noise control engineer with serious interest in sound absorbing technology is advised...

background: one of the most widely used equipments in harvesting hay and grains are four wheel mowers. the aim of the present study was to determine the levels of noise exposure in drivers and bystanders in different states, speeds and gear of four wheel mowers (bcs model 622).   methods: the iso 5131 and iso 6814 standards were used to assess noise exposure in drivers and bystanders, respectiv...

The sound quality inside a car is a very important aspect of automobile design. Many different sources produce sounds that can be heard inside a car. Previous studies have investigated the sound quality of the sources, such as those produced by the engine [1,2], door closing [3,4], and power windows [5,6]. Recent developments in vehicle design have led to a reduction in various sound levels, pr...

The requirements for alarm sounds for safety critical contexts are many, some of which may be conflicting. This study concerns the design of alarm sounds for a hospital environment, in particular operating room conditions. We describe the process of capturing sound design ideas in a form that could be utilised in practical sound design. The process is an application of the Rich UseScenario meth...

The objective of this article is to conceptually transfer the concept of open source software (OSS) development to scientific entrepreneurship and to hypothetically discuss the support potentials of this rather new development philosophy for what we than call open scientific entrepreneurship. Therefore, at first the authors will go into conceptual details of scientific entrepreneurship and than...

purpose is to reduce the unwanted noise from recorded bird sound chip notes, design a scheme to detect differences and similarities between recorded chip notes, and classify bird sound chip notes. The technologies of determining the similarities of sound waves have been used in communication, sound engineering and wireless sound applications for many years. Our research is focused on the simila...
