What is Industrial Noise and Vibration Control?
Industrial noise and vibration control is the application of engineering principles and techniques to reduce the unwanted sound and motion generated by industrial processes and equipment. Noise and vibration can have adverse effects on human health, productivity, quality, safety, and comfort. They can also cause environmental pollution, interference with communication, damage to structures and equipment, and legal issues.
Why is Industrial Noise and Vibration Control Important?
Industrial noise and vibration control is important for several reasons:
Noise and vibration can cause hearing loss, stress, fatigue, annoyance, sleep disturbance, cardiovascular diseases, and other health problems for workers and residents exposed to high levels of noise and vibration.
Noise and vibration can affect the performance, accuracy, reliability, durability, and maintenance of machines and equipment. They can also cause errors, defects, waste, breakdowns, accidents, and injuries.
Noise and vibration can reduce the quality of products and services. They can also affect the customer satisfaction, reputation, and competitiveness of industrial organizations.
Noise and vibration can violate the occupational health and safety regulations, environmental standards, building codes, zoning laws, and contractual agreements. They can also result in complaints, lawsuits, fines, penalties, compensation claims, and loss of goodwill.

What are the Sources of Industrial Noise and Vibration?
Industrial noise and vibration can originate from various processes and equipment that cause impact, vibration, reciprocation, friction, and turbulence in air or gas streams. Some of the common sources of industrial noise and vibration are:
Heating, ventilation and air conditioning (HVAC) systems: These systems can generate noise and vibration due to fans, compressors, ducts, valves, dampers, filters, and other components. The noise and vibration can be transmitted through the air or the structure of the building.
Pumps and motors: These devices can produce noise and vibration due to mechanical forces, fluid flow, cavitation, imbalance, misalignment, bearing wear, and other factors. The noise and vibration can be radiated through the air or the piping system.
Generators: These machines can create noise and vibration due to combustion, electrical currents, magnetic fields, cooling fans, exhaust systems, and other components. The noise and vibration can be emitted through the air or the foundation.
Elevators, garbage chutes and compactors: These equipment can generate noise and vibration due to moving parts, impacts, friction, hydraulic systems, and other mechanisms. The noise and vibration can be propagated through the air or the structure of the building.
Garage doors: These doors can produce noise and vibration due to opening and closing operations, motors, springs, hinges, rollers, tracks, and other parts. The noise and vibration can be transmitted through the air or the structure of the building.
Machinery: Various types of machinery used in industrial processes can cause noise and vibration due to cutting, drilling, grinding, milling, turning, stamping, welding, forging, molding, extruding, mixing, conveying, and other operations. The noise and vibration can be emitted through the air or the structure of the machine.
Vehicles: Vehicles such as trucks, forklifts, cranes, loaders, excavators, bulldozers, and other vehicles used in industrial sites can create noise and vibration due to engines, transmissions, brakes, tires, horns, sirens, alarms, and other sources. The noise and vibration can be radiated through the air or the ground.
How to Measure Industrial Noise and Vibration?
Industrial noise and vibration measurement and analysis are essential for diagnosing the problems, evaluating the impacts, and designing the solutions for noise and vibration control. The measurement and analysis of noise and vibration involve the use of various instruments, techniques, and software tools.
What are the Instruments for Noise and Vibration Measurement?
The basic instruments for noise and vibration measurement are:
Microphones: These are devices that convert sound pressure variations into electrical signals. Microphones can be classified into different types based on their operating principles, frequency response, directional characteristics, sensitivity, and dynamic range. Some common types of microphones are condenser, dynamic, piezoelectric, and electret microphones.
Accelerometers: These are devices that measure the acceleration or vibration of a structure or a machine. Accelerometers can be classified into different types based on their operating principles, frequency response, sensitivity, and dynamic range. Some common types of accelerometers are piezoelectric, piezoresistive, capacitive, strain gauge, and servo accelerometers.
Signal conditioners: These are devices that amplify, filter, convert, or modify the electrical signals from microphones or accelerometers. Signal conditioners can be classified into different types based on their functions, such as preamplifiers, charge amplifiers, filters, integrators, converters, isolators, etc.
Data acquisition systems: These are devices that digitize, store, process, display, or transmit the electrical signals from signal conditioners. Data acquisition systems can be classified into different types based on their hardware and software components, such as analog-to-digital converters (ADCs), multiplexers, counters, timers, memory units, processors, displays, interfaces, etc.
Analyzers: These are devices that perform frequency analysis, spectral analysis, modal analysis, statistical analysis, or other types of analysis on the digital signals from data acquisition systems. Analyzers can be classified into different types based on their functions and algorithms, such as fast Fourier transform (FFT) analyzers, real-time analyzers (RTAs), spectrum analyzers (SAs), octave band analyzers (OBAs), modal analyzers (MAs), etc.
What are the Techniques for Noise and Vibration Measurement?
The basic techniques for noise and vibration measurement are:
Sound pressure level measurement: This is the technique of measuring the sound pressure level (SPL) at a point in a sound field using a microphone and a sound level meter (SLM). The SPL is expressed in decibels (dB) relative to a reference pressure of 20 μPa. The SPL can be measured in different frequency weightings (such as A-weighting or C-weighting) to account for the human perception of sound loudness at different frequencies.
Sound power level measurement: This is the technique of measuring the sound power level (SWL) of a sound source using an array of microphones and an analyzer. The SWL is expressed in decibels (dB) relative to a reference power of 1 pW. The SWL can be measured in different methods (such as reverberant room method or free field method) to account for the sound propagation characteristics in different environments.
Vibration level measurement: This is the technique of measuring the vibration level of a structure or a machine using an accelerometer and an analyzer. The vibration level can be expressed in different units (such as acceleration in m/s2 or g; velocity in mm/s or in/s; displacement in μm or mils) depending on the frequency range and the application. The vibration level can be measured in different frequency weightings (such as linear weighting or exponential weighting) to account for the human perception of vibration severity at different frequencies.
Vibration spectrum measurement: This is the technique of measuring the vibration spectrum of a structure or a machine using an accelerometer and an FFT analyzer. The vibration spectrum is a plot of vibration amplitude versus frequency that shows the frequency components of the vibration signal. The vibration spectrum can be used to identify the sources of vibration, such as imbalance, misalignment, looseness, resonance, etc.
Modal analysis: This is the technique of measuring the modal parameters of a structure or a machine using an array of accelerometers and a modal analyzer. The modal parameters are the natural frequencies, mode shapes
