Airport Noise Control Practices

Hosted at the Seattle-Tacoma International Airport, this course is designed for Airport Noise Officers and other professionals dealing with aircraft noise. It provides an excellent background and discussion of many topics that airport noise officers deal with on a daily basis. The course will cover:

  • Acoustics terminology
  • The effects of noise on people
  • Aircraft noise regulations
  • Noise modeling concepts
  • Public information tools
  • Current events (including PBN implementation)

Course participants will receive course notes, materials that support and expand on material covered in the course.

Lead instructor Brad Nicholas supports projects by performing airline fleet analysis, aircraft noise measurements and analysis, radar data analysis, and aircraft noise modeling. He is an experienced user of the FAA’s Aviation Environmental Design Tool (AEDT), and Braunstein + Berndt’s SoundPLAN. Visit his bio for more information.




Course Outline



Session 1: Airport Noise Terminology – Acoustics

Provides a thorough discussion of the mathematical description of aircraft noise – the acoustics that underlie the noise terminology we use on a daily basis. Specific topics will include: scientific notation, logarithms, sound pressure levels, propagation effects, and the decibel.

Session 2: Airport Noise Terminology – Metrics

Provides a discussion of the noise terminology most commonly used to describe aircraft noise. Specific measures will include: the A-weighted decibel, Time Above, Sound Exposure Level, Equivalent Sound Level, Day-Night Average Sound Level, and Community Noise Equivalent Level.

Session 3: Aircraft Noise Effects and Land Use Compatibility

Covers the effects of aircraft noise on people, including both behavioral and health effects. We also will discuss federal and local guidelines for assessing the compatibility of aircraft noise with land use.

Session 4: Federal Noise Regulations

Covers the federal noise regulations that govern the discussion of airport noise issues, including: NEPA; and FAR Parts 36, 91, 150, and 161.



Session 5: Noise Modeling

Presents an overview of aircraft noise modeling techniques.

Session 6: Aircraft Noise Measurement Techniques

Includes techniques for making noise measurements near an airport, such as the factors that help determine when and where measurements should be made; how to make measurements; troubleshooting in the field; and reporting methodology.

Session 7: Noise Monitoring Systems

Describes some of the permanent and portable noise monitoring systems available on the market. Topics will include procurement techniques; and most importantly, what to do with data from monitoring systems.

Session 8: Sound Insulation

Provides an overview of sound insulation fundamentals.

Who should Attend

HMMH’s two-day Airport Noise Control Practices course is designed to be responsive to the needs of a variety of people involved in issues surrounding aviation noise, including:

  • Airport noise officers
  • Aviation planners
  • Reviewers of environmental documents containing noise exposure maps
  • Preparers of noise exposure maps, including environmental consultants

Past attendees have included professionals and students from across the U.S. and a number of foreign countries; the mixture has provided for stimulating class discussions and group interaction. The course provides an overview of the technical, legal, and practical issues that are important for professionals dealing with airport noise issues. The first day of the two-day course focuses on providing a framework for understanding the issues. The second day focuses on problem solving.

I’ve been to three noise conferences since taking on noise affairs but none have been as beneficial as the two-day course at HMMH.
