PCB® Tips From Techs

Title:

Ultra High Temperature Accelerometers for Aerospace Propulsion

UHT-12 is a new crystal designed for more accurate, lower noise measurements during large temperature variations.

Title:

Surface Microphones

Surface Microphone are used to measure true surface pressure and noise. The surface microphone and pad design
are optimized for confined spaces and to reduce wind induced noise during testing.

Title:

Microphone - Safe Handling and Maintenance

Test and measurement microphones are very delicate instruments. Learn how to protect and maintain your microphones by following these safe practices and maintenance recommendations.

Title:

Array Microphone Overview

Array microphones are a cost effective method to take acoustic measurements in applications such as sound pressure
mapping, beam-forming, holography, noise source location and machinery monitoring.

Title:

Probe Microphone Overview

Probe Microphones are recommended for sound pressure measurements in confined areas and high temperature applications.

Title:

Comparison of 1/4" & 1/2" Condenser Microphones

Learn how to identify the appropriate applications for 1/2" and 1/4" Condenser Microphones.

Title:

How to Avoid Sensor Cabling Problems

There are two primary causes of problems with sensor cabling - connecting the sensor to the cable and cable strain relief.
In this "Tips from Techs", learn how to avoid problems with intermittent sensor signals and cable failures.

Title:

LabMaster Professional 3200 for fastener torque angle tension testing

Title:

Microphones - Externally Polarized vs. Prepolarized

When should Prepolarized microphones be used for acoustic test measurements?
Learn the differences between traditional, externally polarized microphones and new modern prepolarized microphones.

SAAMI Training Seminar

Title:

Decibel Addition in Acoustic Testing

Learn about the logarithmic properties of sound and decibel addition from Dr. Andrew Barnard. Find out how this
is used to assess and reduce noise.

Title:

Transmission Loss in Acoustic Testing

Dr. Andrew Barnard shows how to test materials for sound absorption and loss. Learn how choose the best materials
for noise reduction. These techniques are used by automobile and aircraft manufacturers to reduce effect
of sounds from outside sources such as wind and other noise.

Title:

Noise Floor Calculations in Acoustic Testing

Dr. Andrew Barnard shows how use Noise floor calculations to when testing to discover sources of unwanted noise when
designing products. This is typically used in testing for the automotive industry and computer components such as disk drives.

Title:

Directivity Patterns in Acoustic Testing

Dr. Andrew Barnard demonstrates how Directivity patterns and theory is used for noise source location, beamforming, holography
and sound power mapping. Directivity is used for of Acoustic product testing
in the loud speaker, automotive and aerospace industries.

Title:

Anti-aliasing in Acoustic Testing

Dr. Andrew Barnard demonstrates the principals of Anti-Aliasing and explains how high frequency microphone signals
can become indistinguishable.
