  • Sensitivity Testing

    Response Dynamics Vibration Engineering, Inc.

    Sensitivity testing involves making predictions of system response to environmental disturbance. The significance and importance of the system sensitivity estimates is very often overlooked. This gets companies in trouble and is one of the top reasons why we are called upon to provide timely solutions. Most teams are focused on getting their product to work and get it out the door. An engineering team will often not know how to quantify what to expect in the customer environment and how to test for those expected disturbances. We design hundreds of sensitivity tests and can explain the important concepts to consider in designing the tests and making the right measurements that allow for sound estimates of system response. This is an important expertise we use in our vibration, acoustic and magnetic field consulting services.

  • Vibration Meters

    PCE Instruments

    A vibration meter is used in manufacturing for machine condition monitoring, product testing and quality assurance. Many machine maintenance technicians use vibration meter devices in tandem with sound level meters to analyze frequency. A vibration meter also can be used in civil engineering to measure the vibration of structures such as buildings, roads and bridges. In addition, specialized vibration meter devices can be used to measure the vibration of the human body. Any vibration meter will measure one or more of the following parameters: vibration acceleration, vibration velocity (speed) and / or vibration displacement.A vibration meter is typically a portable device with a memory for storing measurements. Most vibration meter models feature a built-in data logger for collecting and recording vibration measurement data over time. In this way, vibration measurement data can be acquired with great precision.

  • Digital Audio Analyzers

    WinTek s.a.s.

    As regards the activity carried out by those in the call center it is important to note that much of the noise under which a trader is directly applied to the outer ear (acoustic signal from the headphone) and not, as usually happens, is only widespread environmental noise . For this reason they are different measurement methodologies normalized been identified that provide for a correction of the measured noise spectrum waves bring the same extent equivalent to the diffuse sound field in the vicinity of the attache head. The measurement techniques normalized are two: the first requires the measuring the acoustic signal with a probe placed in the operator''s ear canal (MIRE technique) but attention difficult to enforce; the second requires the measurement of an acoustic signal to the eardrum equivalent to that to which the operator is subject by the use of a system similar to those used in headphones, powered by an equivalent electrical signal and applied to a normalized anthropometric mannequin.
