One day seminar! August 7, 2018

Sound Metrics Unleashed

Sound quality isn’t just for “gurus” anymore!

You are cordially invited to the “Sound Metrics Unleashed!” seminar taking place August 7, 2018 at the Siemens PLM office in Cincinnati, OH.

This interactive seminar, full of practical examples and interesting sounds, will answer questions like:

  • Why doesn’t the decibel level “dB” match my subjective impressions of the sound?
  • What are all the different sound metrics (loudness, roughness, tonality, etc) and how are they useful?
  • What is the best metric to use to describe the sound I am hearing?
  • How do I reduce the sound metric to a single, meaningful number?

Lunch is provided and the seminar is no cost to attend.
