OUR JOBS AND SERVICES

     DYNAMIC TECHNOLOGIES, Ltd. is a high tech engineering firm was established in 1992 year and is based in Moscow, Russia. We offer wide range of services in branches:

-  practical sound, noise & vibration reduction;

-  sound, noise & vibration control, calculation on work place and environment;

-  development of devices for sound, noise & vibration attenuation;

-  design of technologies for sound, noise & vibration level reduction;

-  development of devices and technologies of sound & vibration industrial usage and application;

-  measurement of reverberation time of halls. auditoriums, studios for its acoustics property estimation.

   

     DYNAMIC TECHNOLOGIES, Ltd. handled all projects, small or large, with professionalism and commitment to client satisfaction.

     Modern acoustic measurement techniques produce many thousands of data during short time of test. One must have suitable approach to discover links between this data and vibration/sound field and to solve by this manner the vibroacoustic problem. Our work experience, methods of acoustic data acquisition and data investigation give us more results then only complete techniques used for acoustic measurements.

The range and some results of our activity:

  • The MEAN FOR CIRCULAR SAW NOISE REDUCTION (patented) for wood-, stone- and metal processing by circular sawing machine with 1 or more circular blades. Carried into practices in 3 furniture fabrics. Obtained noise reduction is 18 dBA (depends of applied woodwork technology and equipment).
  • Recommendation development for metalprocessing tools noise attenuation on State “Moscow Monetary Mint” Factory.
  • Structure-generated noise reduction in room (1 floor up) from machinery camera with 3 air- refresh compressors of the large food store. Result of our job is 12 dBA noise reduction.
  • Designing and production of vibro-damping handless of vibro-instrument for road-repairing company. Vibration reduction is 9 dB.
  • Expertise of sound-, noise-, vibro-activity of consumer goods for "IZVESTIA" newspaper (one of largest in Russia, 1200 k copies/day); for the Consumer Right Suppîrt Society.
  • The noise decreasing of large ventilation installation for air/wood dust separation from their mixture in wood- processing factory. The environment noise reduction on distance 200 m is 7 dBA.
  • Practical reduction of noise and vibration of compressors, ventilation systems, refrigerators;
  • The concrete block vibro-forming technology improvement (including usage of 300 vibro-exciters) in the Building Material Plant.
  • Projecting of windows with special noise isolation requirements for a new 24-floor building.
  • Annual training course “Acoustic ecology” (lectures, seminars) for post-graduated students of Ecological Division of Moscow States University (MSU) – since 2002 yr.

Our job condition for sound, noise and vibration measurement/reduction/usage:

  1. All jobs complete according standards, norms, rules or customer specific technical requirements;
  2. All jobs complete, if possible, on act equipment without breaks and pauses in work.
  3. All jobs complete, if possible, without change of existing customer technology.
  4. All jobs complete, if possible, with low costs for customer. To avoid customer of extra costs we’ll take into account only most effective and cheep methods, technologies of noise & vibration reduction/usage to prevent increasing of time, size and price of the job.

At the end of the job our customer will get (on choice):

Ø       Protocol of sound, noise, vibration measurement;

Ø       Expert resume with comparison results of measurement with standards, norms or customer specific technical condition;

Ø       Recommendations, project description of technologies for sound, noise & vibration reduction/usage;

Ø       Details, devices, equipment, technologies for sound, noise & vibration reduction/usage.
