This seminar is designed for those starting to learn noise engineering, providing a comprehensive understanding from fundamentals to practical applications.
It clearly explains the meaning of decibels and sound pressure levels, correct measurement methods, and the concept of frequency analysis using FFT.
In addition, it systematically organizes and explains noise generation mechanisms and countermeasures (sound absorption, sound insulation, and vibration isolation).
You can acquire the fundamental skills of a noise engineer who can “measure, interpret, and solve” within a single day.
Do you have any of these issues?
- You are not confident in your understanding or handling of decibels
- You cannot determine where measurements should be taken
- You are unsure how to distinguish between sound absorption, sound insulation, and vibration isolation
- You cannot obtain reproducible measurement results in the field
- You do not understand what FFT frequency analysis results actually mean
Target participants
- Design, development, research, production engineering, and maintenance personnel who need to work with noise and acoustics
- Those assigned to noise measurement or evaluation but uncertain about decibels, sound level, or sound pressure level
- Those who do not know how to interpret FFT or frequency analysis results
- Those who want to select and evaluate countermeasures such as sound absorption, insulation, and vibration isolation based on engineering principles
- Those who want to apply consistent measurement, evaluation, and countermeasure techniques in real-world work
Overview of the seminar
This seminar systematically explains noise engineering from fundamentals to practical applications for engineers beginning in this field. First, participants understand the difference between sound and noise and the essence of noise problems, then correctly grasp fundamental concepts such as decibels, sound pressure level, and A-weighting. Next, it organizes reproducible measurement methods and evaluation approaches, and explains the meaning and usage of FFT-based frequency analysis. Furthermore, it clarifies noise generation mechanisms such as structural, aerodynamic, and rotating machinery noise, and develops practical skills in countermeasures (sound absorption, sound insulation, vibration isolation) from the perspectives of source, transmission path, and receiver. This enables participants to make appropriate decisions in real engineering situations.
・Fundamentals: difference between sound and noise, and the essence of noise problems
・Basic engineering knowledge: decibels, sound pressure level, A-weighting
・Measurement methods and evaluation principles with reproducibility
・Frequency analysis using FFT and interpretation of spectra
