Two Half-Day Courses on Acoustics in Multifamily Construction
Instructor: Pablo Daroux, Wilson, Ihrig, and Associates, Inc., pdaroux@wiai.com , instructor bio
Times and costs:
2 pm – 5 pm Sunday (for acoustics design professionals), $175 members, $225 non-members
3 pm – 5 pm Wednesday (for architects), $100 members and non-members
Description:
- Sunday afternoon course for acoustic design professionals: This course is intended for the acoustics design professional interested in furthering his or her understanding of the various issues involved in the design of multifamily construction: from the initial noise survey of the site to determine exterior noise mitigation and building shell design requirements, through the many interdwelling sound and impact isolation issues and solutions involved, to practical techniques for the control of noise and vibration due to mechanical and plumbing building services. Numerous examples will be provided as well as schematic details of practical solutions to common issues. Common construction errors will be presented from several litigation cases.
- Wednesday afternoon course for architects: This course is intended for the practicing Architect interested in furthering his or her understanding of the various acoustics issues involved in the design of multifamily construction: from the design requirements of sound walls to control exterior noise through special building shell components, the many interdwelling sound and impact isolation issues and solutions involved, to practical techniques for the control of noise and vibration due to mechanical and plumbing building services. Numerous examples will be provided as well as schematic details of practical solutions to common issues. Common construction defects from several litigation cases and ways to avoid or minimize those will be presented.
Statistical Energy Analysis of Noise and Vibration Problems
Instructor: Dr. Bryce Gardner, ESI, bryce.gardner@esi-group-na.com, instructor bio
Time: 9 am – 4 pm, with lunch break from 12 pm – 1 pm
Early registration cost: $350 members, $425 non-members
Late registration cost: $450 members, $525 non-members
Description: Predicting the transmission of noise and vibration through practical structures of engineering interest, across a broad frequency range, presents a number of challenges to an analyst. This course will provide an overview of modern predictive SEA methods, discussing the physics of high frequency noise and vibration transmission from both modal and wave viewpoints. The derivation of the underlying SEA equations will be discussed and the parameters used in an SEA model will be summarized. Particular emphasis will be placed on the theoretical aspects of the wave approach to SEA; the physics of wave propagation in commonly encountered structural and acoustic subsystems will therefore be discussed in detail. The calculation of the parameters that govern vibro-acoustic energy input, storage, transmission and dissipation will be discussed. New developments in SEA will be presented including the coupling of SEA with finite elements analysis (FE). ESI’s VA-One software will be used to demonstrate the methods described in the course.
INCE fundamentals exam preparation and optional exam
Instructor: James Barnes and Eric Wood, Acentech, jbarnes@acentech.com, ewood@acentech.com, instructor bios
Time: 9 am – 1 pm (course), 2 pm – 4 pm (fundamentals exam)
Early registration cost: $100 associate members, $150 non-members
Late registration cost: $150 associate members, $200 non-members
Description: If you are considering taking the INCE fundamentals exam as one way to become a full member of INCE, this course is aimed at helping you understand and prepare for the exam. The exam is a two- hour, closed-book, multiple-choice examination with 75 questions drawn from the fundamentals of acoustics and noise control engineering. Qualitative questions with descriptive responses and quantitative questions requiring only simple calculations are included in the examination. The purpose of the examination is to evaluate an individual's background in the field of noise control engineering. In this preparation course you will learn about the nature of the exam questions and responses and the wide range of concepts and topics covered. A minimum of mathematics will be included.
If you feel comfortable with the material presented in the course, you may stay and take the actual fundamentals exam from 2 – 4 pm.
