Acoustical Services

During the last 30 years our office has developed a nationwide reputation for technical excellence. We are thorough in meeting regulations and in preparing complete and accurate documents, and are effective in speaking and listening to the public.
 
Our office includes 8 people, 6 of which are full-time, in-house, senior acoustical engineers. We are associated, on a permanent basis, with technical, production and support staff, as required by specific project needs.
 
We are, by far, the best-equipped acoustics and vibrations laboratory in Israel. We have the capability to make simultaneous, detailed, long-term measurement at 10 locations with 6 channels producing spectral analysis at any required bandwidth. We have 6 computer workstations with all the latest versions of the software that is required to calculate and predict noise for airports, heliports, trains, road traffic and industrial plants and areas. In addition we have proprietary software, developed by us, for our own use, to handle complex problems and to facilitate data reduction.
 
 
Following is a representative list of clients and projects in our main areas of work. Full list will be delivered upon request.
 
Acoustic Measurements
 
Acoustic measurements form the basis for the description of the noise and vibration climate, in which we live and operate. They are also the anchors for all calculations and prediction of the future climate that results from implementation of development plans. Since, in many cases, the future design goals and criteria are based on the existing acoustic environment, accurate and comprehensive measurements are essential in order to define the noise abatement needs of the projects and to insure the best possible benefit to noise ratio. Our office is equipped with state-of-the-art, professional measurement systems that allow us to measure both temporal and spectral characteristics of noise and vibrations from all sources for any length of time. All our measurement systems are capable of storing and processing long term data for subsequent analysis on our work stations.
Our in-house systems include:
   *      4 Larson Davies model 870 Noise Analyzers
   *      3 Larson Davies model 2900 dual channel Real time Spectrum Analyzers
   *      3 All weather microphones systems
   *      Noise production systems
   *      Proprietary and commercial noise and vibration data reduction software.
 
 
Transportation Systems
 
As transportation planning moves increasingly into intermodal planning and design, our office addresses noise problems for multiple systems within a common geographic area. Our office offers noise and vibration control solutions for existing transportation systems and provides design solutions for new facilities both during and after construction.
Our office regularly evaluates both operational and construction noise and vibration impacts for transportation projects related to airports, highways, rail transit systems and ports as well as for other public works projects. These projects typically involve baseline measurements to characterize existing noise and vibration sources, projections of future conditions, assessment of impact based on applicable regulatory requirements and appropriate criteria, and the recommendation of practical measures to mitigate impacts, if needed. We are experienced at preparing documentation for environmental impact statements and reports and communicating effectively with the public at project meetings and forums and with all the levels of the planning establishment.
