Course #2: Industrial noise calculations with CadnaA (Vendor Course)

Instructor: Arne Scheck - DataKustik,

Day: Sunday August 19 2012

Time: 8:00 am - 12:00 pm

Location: Marriott Marquis (room to be determined)

Cost: No Cost

Description: The course is for people interested in industrial noise calculation. The participants don’t need to be user of any noise calculation program. During one half day, participants will be shown the state of the art in modeling, organizing and calculating noise according to relevant guidelines such as ISO9613-2.

The course will consist of the three parts modeling, project organization and calculations. For these parts, general concepts will be explained generically and illustrated with the software package CadnaA.

Modeling: during this part of the course, attendees will learn strategies for noise source modeling in industrial contexts as well as how to obtain emission data. It is shown that with modern software packages, emission data can even be obtained when measurements of the spectra aren’t possible; the spectra can automatically be generated from parameters such as the nominal power of a motor.

Project organization for large industrial projects, it is vital to organize objects hierarchically, i.e. in a tree structure. We show the benefit of this approach and how to execute it with CadnaA.

Calculations: Calculations must be fast and reliable. In CadnaA, this is the case. We show calculation possibilities including effects like meteorology.

Course #7: Sound propagation - an impedance based approach

Instructor: Dr. Yang-Hann Kim, KAIST

Day: Thursday August 23 2012

Times: 8:00 am - 5:00 pm

Location: Marriott Marquis (room to be determined)

Cost: No cost student registrants, but students must purchase Sound propagation, an impedance-based approach, from Wiley. Dr. Kim will arrange for books to be at the short course.

Description: The course introduces acoustics and sound fields by using the concept of impedance. It starts with vibrations and waves, demonstrating how vibration can be envisaged as a kind of wave, mathematically and physically. One-dimensional waves are used to convey the fundamental concepts. It attempts then to understand wave propagation in terms of characteristic and driving point impedance. The essential measures for acoustic waves, such as dB scale, octave scale, acoustic pressure, energy, and intensity, are explained. These measures are all realized by one-dimensional examples, which provide mathematically simplest but clear enough physical insights. The course then moves on to explaining waves on a flat surface of discontinuity, demonstrating how propagation characteristics of waves change in space when there is a distributed impedance mismatch. Next is a chapter on radiation, scattering, and diffraction, where we will show how these topics can be explained in a unified way, by seeing the changes of waves due to spatially distributed impedance. Lastly, we will cover sound in closed space, which is considered to be a space that is surrounded by spatially distributed impedance, and introduces two spaces: acoustically large and small space. The bulk of the course and course material is concerned with introducing core fundamental concepts, but the appendices are included as the essentials as well to cover other important topics to extend learning.

Course #12: Sound quality (Vendor Course)

Instructor: TBD, Bruel and Kjaer

Day: Thursday August 23 2012

Times: 1:00 pm - 5:00 pm

Location: Marriott Marquis (room to be determined)

Cost: No Cost

Description: The sound quality of a product is of ever-increasing importance when assessing the total quality of the product. For products ranging from cars to hand tools, from medical devices to golf clubs, not only the level but also the quality of the sound it makes is part of what attracts or repels the customer. Poor sound quality can lead to higher warrantee costs and poor sales, the right sound can lead to increased sales. Many factors come into play in the sound quality evaluation process. Traditional objective measuring and analysis methods, such as A-weighted sound pressure and FFT analysis, are not enough to analyze product sound. Customer expectations and jury testing are also important factors for determining acceptable sound quality because, in the end, only the human ear of the customer can tell the designer whether or not the product has the right sound. Attend this session to learn the basics of Sound Quality and how to improve the sound of your products.

Course #14: Buy-Quiet Procurement Strategies

Instructor: David Nelson, Nelson Acoustics

Day: Thursday August 23 2012

Location: Marriott Marquis (room to be determined)

Cost: $50 USD (early registration, before 07/12/2012) -- $100 USD (after 07/12/2012)
