Hearing is Believing Example Projects

The Interactive Sound experience can directly answer everybody's fundamental question, "what will this sound like at my place?& quot; Evidence is delivered as acoustic examples, minimizing the need for technical explanations. One client said, "This was one of the most cost-effective decisions we ever made. Using ISe made all the difference in getting the required approvals from so many different decision makers". Listeners gain an experiential under- standing of noise issues. A decision maker can hear the differences among noise management options and exactly how much relief is offered by mitigation proposals. This presentation strategy has been proven in hundreds of decision making settings in the United States and other countries.

The interactivity of the program expands on conventional ways for presenting noise information. A presenter can change the direction of a program to meet audience needs and can use the system to respond to, "What if?" questions.

Noise management issues often relate to specific projects. ISe presentations can be readily customized by addition of local images, maps and sounds. The system has been designed to be independent of both the language in which presentations are made and the noise metric systems being illustrated. For example, the European versions of ISe reflect the EU guidelines for noise metrics and mapping.

Military Noise Management

Programs have been developed for all branches of the US military for use in training and community involvement. Topics include both aircraft and ordinance. The sound reference library includes a broad collection of aircraft and weapon systems. Some presentations emphasize planning for compatible land use, customized to reflect the setting of individual installations.

The High Speed Train

A presentation was developed for the California High Speed Train Authority. Sound levels were based on measurements made for trains in Europe and Asia. Field recordings were then integrated into the ISE framework. An audience could experience passby sounds and images of conventional and high speed trains under different listening conditions.

Airport Expansion

Proposals to add or extend run- ways can be controversial. The ISe format is an excellent way of depicting acoustic change to concerned persons. Virtual reality scenes, with sound, are used to create animations depicting changes in runway configuration and the sounds of overflights by different aircraft.

Highway Noise and Barriers

The FHWA commissioned a program that presents roadway noise management issues. It includes a basic roadway noise calculator; based on vehicle numbers, type, speed, distance and surface conditions. It also includes an interactive barrier design feature with acoustic examples modified by distances and barrier height.

Transit and Train Noise

A custom program using ISe technology was commissioned by a consulting firm, EAI, Inc. It includes recordings and video of a library of transit and other rail noise sources. The program has been further customized to address specific client noise management and visual impact issues. The program has won awards from several professional organizations.

Natural Quiet in Parks

Presentations emphasizing the protection of natural soundscapes have been developed for several national parks; Minuteman Historic park, Grand Canyon, and Grand Tetons. The programs permit the mixing of background sounds, sounds made by wildlife, and a variety of sounds of human park activities.

Industrial Facilities

Projects have include industrial and resource extraction activities including; recycling, quarrying, oil production and commercial winemaking. A number of these projects have included collection of field data, model development, and design of presentations for use in public hearings.

Other National Settings

Programs based on ISe technology have been employed in a variety of national settings. In each case the presentations have reflected the noise standards and metrics suitable to the location. In several cases the presentations have been produced in languages other than English. Presentations have been develop for use in Australia, Canada, the UK, Germany, France and Hong Kong.
