Noise Control Master Class

Nelson Acoustics’ Noise Control Master Class provides online noise control training designed to convey practical knowledge in a short time using math no more advanced than logarithms.

Learn from a respected professional how to anticipate noise problems, identify the cause, prioritize the treatments, and confidently communicate the solutions to others.

Classes Available Now: Week of January 20, 2025

• Fundamentals 1.1: Understanding Acoustics:  4 hrs  $400  – Why sound happens, how we measure it, how we describe it, how we perceive it, and why that’s confusing.
  • Acoustic waves vs mechanical action
  • Frequency, harmonics, wavelength, spectrum
  • Magnitude, levels, decibels (definitions, adding and subtracting)
  • Perception
  • Sound Power vs Sound Pressure, propagation, weighting networks (dBA and dBC), frequency bands

• Fundamentals 1.2: Understanding Noise Control:  4 hrs  $400 – Reducing sound through low-noise design, source modification, barriers and absorbers; setting priorities, assessing progress.
  • PREREQUISITE: “Understanding Acoustics” or equivalent
  • Zero in: Prioritize what to work on, what can be ignored
  • Concepts: Noise as waste byproduct, the cost of noise is not zero
  • Focal points: Design, Source, Path, Receiver
  • Materials and Methods: Absorption, Barriers, Partitions, Enclosures, Vibration isolation and damping
  • Do’s and Don’ts

Each Class meets in two sessions on it’s given day: 10 AM – 12 PM and 1 – 3 PM (US Central Time) 

Courses TBD:

• Assessing Industrial Noise in the Community – Methods for assessing annoyance of noise in communities surrounding industrial facilities.
• Forecasting Industrial Noise in the Community – Strategies and methods for estimating noise levels early in the design process, mitigating it as necessary to enhance compatibility.
• Industrial Noise Control for the Workplace – Strategies and methods for conserving hearing through noise control and “Buy-Quiet” methods.
• Low-Noise Product Design – Designing a product’s sound to send the “right” message, and how the “right” message gets determined.
• Managing Cooling Fan Noise – Integrated design strategies for reducing cooling fan noise.
