Factory Noise Measurement: Process, Standards And Professional Services From DASM

Factory noise measurement service – noise survey and evaluation is conducted by DASM acoustics experts in accordance with QCVN, ISO, TCVN standards using international calibration equipment, providing fast – accurate – reliable results.

Why is factory noise measurement necessary?

Noise is one of the significant harmful factors in the industrial working environment. Not only affecting workers' health (especially hearing and psychology), noise also reduces productivity, causes fatigue, reduces concentration, and can lead to occupational accidents.

Why Must Manufacturing Plants Control Noise?

DASM Institute determines chiller noise for a leading Japanese manufacturing plant in Thai Binh

In addition, according to current regulations in Vietnam, enterprises have the obligation to assess and control noise in the working environment and around the factory in order to ensure compliance with laws on labor safety and environmental protection.

Regulations and standards for industrial noise measurement

Currently, noise measurement in workshops, factories, and industrial zones must comply with the following technical standards:

• QCVN 24:2016/BLĐTBXH: National technical regulation on noise at the workplace
• QCVN 26:2010/BTNMT: National technical regulation on environmental noise
• ISO 9612: Acoustics – Determination of occupational noise exposure – Engineering method
• ISO 11690: Acoustics – Recommended practice for the design of low-noise workplaces containing machinery
• TCVN 7878-1:2018 (ISO 1996-1:2016): Acoustics – Description, measurement and assessment of environmental noise – Part 1: Basic quantities and assessment procedures

The above standards require measurement at the correct locations and times, using calibrated equipment and complete reporting for comparison with permissible limits.

When is it necessary to measure factory noise and industrial noise?

Enterprises should carry out factory noise measurement in the following cases:

• When constructing or operating a new workshop
• When there are complaints from workers or surrounding residents
• Before and during environmental and labor safety inspections
• According to the factory's periodic monitoring plan
• When changing production lines or machinery that may increase noise levels

Proactive noise measurement helps businesses prevent risks, improve the working environment, and demonstrate professionalism in management.

DASM's factory noise measurement process

DASM is a leading prestigious unit in the field of acoustic measurement, owning a VILAS-standard laboratory, international calibration equipment systems, and an experienced team of engineers. Below is the noise measurement process implemented by DASM:

Preliminary survey

DASM specialists will survey the current status of the workshop, determine the areas to be measured, and propose a number of measurement points suitable for the area and structure.

Determine the number of measurement points

According to standards, on average every 10m² corresponds to 1 measurement point. However, the number of points can be adjusted according to specific requirements and actual conditions (machinery locations, high noise areas, etc.).

Noise measurement

• Measurement time per point: at least 10 minutes or more to ensure representative data
• Equipment used: specialized sound level meters calibrated periodically

Data processing and analysis

After measurement, data will be analyzed to assess the level of standard exceeding (if any) and provide characteristic acoustic parameters such as: LAeq, Lmax, Lmin, LA90, etc.

Reporting and consulting

DASM's measurement result report includes complete:

• Location, time, and measurement results of each point
• Noise level chart
• Comparison with limits in standards
• Proposing sound solutions for noise reduction with appropriate types of sound insulation – sound absorption materials (if thresholds are exceeded)

How much does factory noise measurement cost?

The noise measurement cost of DASM Institute depends on:

• Number of measurement points
• Survey location (inner city or suburbs)
• Complexity of the space (multi-floor, many machines, etc.)
• Reporting requirements (English required, in-depth, etc.)

DASM will conduct a survey and provide a detailed quotation before implementation. Committed to reasonable – optimal – transparent costs.
