Case study Case Studies

Verification of vehicle interior noise

  • Automotive parts
  • IEC standard
  • Vibration test case study

Test overview

■ Purpose

Reproduce vehicle running vibrations using several small testing machines to check interior noise, interior creaking noise, etc.

EUT

Finished vehicle *The image is below.

■ Test conditions

Measured road noise
Acoustic evaluation by microphone, sensory evaluation in seating, etc.

Advantages

Input vibration can be easily switched between general roads, highways and rough roads simply by operating a PC.
Repeated measurement is possible.
Pulsation conditions can be changed arbitrarily, e.g. single wheel, front wheel, four wheels, simultaneously, etc.

EUT: Front-wheel vibration/Four-wheel vibration

Memo

Facilities used

Compact vibration test system: m-series
Acoustic measurement equipment: microphones, sound level meters, measuring instruments ( DS-3000 made by Ono Sokki), acoustic analysis application (Ono Sokki O-scope made by Ono Sokki)
