MEMTECH ACOUSTICAL offers a wide variety of training classes for engineers, skilled tradespeople, technicians or managers who are involved in taking noise or vibration readings, performing noise surveys, or in solving noise and vibration problems. These classes can be held at your facility, at MEMTECH’s office in Rochester, Michigan, or at an offsite venue of your choosing. Our Six Sigma Black Belt Certified staff have extensive experience in acoustic measurements, noise and vibration analysis and signal processing. We also have licensed professional engineers who can provide exceptional training in the fields of legal noise compliance and advanced acoustics. Our classes are highly “hands-on” and interactive. We can also assist in making measurements and performing analysis in your plant or office areas. We are more than happy to tailor our classes to meet the needs of your specific facility and/or requirements.

Basic Noise Measurements (NM 101)
This is a one-day class for engineers, employees and managers. It provides a basic introduction to acoustics and the use of a sound level meter. Participants are encouraged to bring a sound level meter that they will be using for measurements, or MEMTECH can supply a meter if necessary. Students will be instructed in making accurate sound measurements in both indoor and outdoor situations, including verifying OSHA compliance, as well as identifying noise sources and quantifying hearing-loss concerns.
The material includes:
- The Basics of Acoustics
- Introduction to Sound Level Meters
- Calibration
- Noise Standards and Criteria
- Identification of Noise Sources
- Common Pitfalls in Making Noise Measurements
- Noise Annoyance Issues
- Reporting Data
Hearing Loss Mitigation and Noise Control Management (NM102)
This one-day class provides a strong background for managers, health and safety personnel, and engineers involved in the implementation and oversight of noise control programs in plants and commercial facilities. Issues relating to OSHA and/or NIOSH mandates for employee noise exposure are covered in-depth, along with reporting and documentation requirements. Concerns with environmental (neighborhood) noise compliance, including city and state noise codes are also included.
Topics covered include:
- The Basics of Acoustics
- Employee Noise Exposure Legal Requirements and Criteria
- Noise Compliance Measurements
- OSHA Reporting Requirements
- Noise Control/Reduction Methods
- Establishing a Noise Control Program in Plants and Commercial Operations
- Environmental Noise Issues
- Compliance with City and State Noise Codes
- Environmental Noise Control Methods
Advanced Noise Measurements (NM103)
This is a one-day class for engineers, hourly employees and managers who already have a good understanding of basic noise theory and measurements. It is intended to augment skillsets to include advanced techniques in both time and frequency-domain measurements and analysis, and a foundation in data analysis and problem solving.
The material includes:
- Near and Far Field Measurements
- Octave Band and FFT Analysis
- Transfer Functions
- Measuring Sound Transmission Loss
- Advanced Environmental Noise Measurements
- Statistical Methods of Noise Analysis
- Time-Domain Analysis
- Quantifying Noise Reflections and Reverberation
Comprehensive Noise and Vibration Measurement and Analysis (NM104)
This week-long class is intended for engineers or advanced skilled trades who wish to become highly proficient in both noise measurements and basic noise-related problem solving. It is a highly “hands-on” course which allows the participants to take readings and recommend cost-effective solutions in a variety of situations. This class requires the use of both a sound level meter and a 2- channel signal analyzer. Students are encouraged to bring their own equipment, or MEMTECH can provide them for the class.
It includes all the material covered in NM 101 and NM 102, plus:
- Near and Far Field Measurements
- Intermediate Acoustic Theory
- Types of Microphones and Applications
- Noise Control Materials and Their Applications
- Reverberation Control in Rooms and Auditoriums
- Noise Control in Manufacturing Facilities
- NVH Measurements for Product Engineering
- Basic Vibration Measurements
- Environmental Noise Control
- Multi-Channel Analysis Methods (Cross-Spectrum, Advanced Transfer Functions and Coherence)
- Sound Power Measurements
NOTE: This class can be truncated to a 3-day length if the participants have a strong background in noise measurement, and/or have already taken NM 101 and NM 102.
Basic Vibration Measurements (NM105)
This is a two-day class for engineers, employees and managers. It provides a general introduction to making accurate vibration measurements on manufacturing equipment. Participants are encouraged to bring an analyzer or data collector that they will be using for measurements, or MEMTECH can supply the needed equipment if necessary. Students will be instructed in making accurate vibration measurements in a variety of situations, including assuring compliance with equipment vibrations standards, using vibration as a predictive maintenance tool and in understanding the effects of vibration on noise levels. In addition, issues such as vibration-induced machine failures or part quality concerns will be covered.
The material includes:
- Basic Vibration Theory
- Vibration measurements as a predictive maintenance tool
- Types of Sensors and Applications
- Analyzer Setup and Functions
- Connections and Mounting Sensors
- Time domain and FFT measurements
- Trending and Special Algorithms used in Vibration Analysis
- Solving Vibration Problems on Machinery
- Cause/Effect of Vibration and Noise
- Validating data
Data Acquisition, Analysis and Problem Solving (NM106)
This is an intensive 3-week class intended for dedicated engineers who want to improve their data analysis and problem-solving skills. The training is broken-up into three four-day sessions with a recommended period of 3-4 weeks between sessions to allow some practice and application in the material which has been covered.
This class offers a very pragmatic and applied approach toward problem-solving, rather than delving into extensive mathematical and statistical theory. This will empower participants to focus on the practical execution of test planning, analysis and hypothesis-based solution methods when tackling difficult problems.
Problem-solving is a complex, systematic thinking process; it is a constantly evolving and maturing skill. In addition, it is not a discipline that is well-suited for all technical personnel. Effective problem-solving requires sustained hard work, focus and a dogged determination to get to the bottom of complex issues. Therefore, we strongly advise against selecting large groups of engineers or entire departments for participation in this class. The best results will be achieved by selecting key individuals in your organization who are enthusiastic, have a true hands-on and proactive mentality, and who are willing to put in the extra effort to solve difficult problems.
At the end of the course, participants will be able to:
- Plan and organize effective tests, with a focus on root-cause identification techniques
- Develop hypothesis-based test strategies, to systematically identify and eliminate potential problems and failure modes
- Confidently gather a large variety of performance and reliability data and accurately quantify the quality of the data (a topic which is rarely addressed in training)
- Operate multi-channel signal analysis systems, including the use of time and frequency domain methods, cross-channel and transfer functions, statistical data processing as well as basic modal analysis and coherence tests.
- Apply Six Sigma and other statistical methods to optimize and filter the raw datasets, to identify failure mechanisms and eliminate noise factors and/or unwanted data artifacts
- Understand the application of mathematical models, such as Accelerated Life Testing, Weibull analysis, and Systems’ Modeling.
- Hypothesize and validate proposed solutions.
- Present and sell solutions to management
This course requires a significant commitment from both attendees and their management team. Third-party analysis software and a laptop computer is required for all participants. Contact us for details.
A number of additional advanced classes are available to support engineers and technical staff in improving their analytical and problem-solving skills for noise issues, including Product Engineering NVH classes. Contact us for details.
