Test method for the determination of noise emitted by earth-moving machinery

The material testing procedure Determination of noise emitted by earth-moving machinery provides useful information to determine priority noise control measures; monitor equipment condition, early detection of signs and causes of damage... to proactively maintain machinery; production – effectively improving products.

Overview of the Test Procedure for Determination of noise emitted by earth-moving machinery

Test name: Determination of noise emitted by earth-moving machinery.

Test method: ISO 6395:2008: Earth-moving machinery – Determination of sound power level – Dynamic test conditions [1].

Performed at: Construction site.

1. Objective and test subject

– Test objective

Determine the noise emitted by earth-moving machinery.

– Test subject

Earth-moving machinery/construction machinery. They vary greatly in types.

2. Experimental procedure

Steps to perform:

• Equip fully with devices, microphones, and measurement samples.
• Perform sample measurement.
• Process and report results

3. Notes

– In addition to evaluating the noise emission level of the machine to the surroundings, the evaluation of noise levels in each area and the assessment of the effectiveness of noise reduction measures for construction machinery can also be carried out at the measurement site.

– Some notes for the measurement site:

• The machine travel path can select 1 of the 3 following options:

* Hard reflecting surface (concrete/ non-porous asphalt concrete):

+ Wheeled machines, all operating modes

+ Excavators, all operating modes

+ Crawler loaders, fixed hydraulic operation mode

+ Rollers, all operating modes

* Combination of hard reflecting surface and sand: The machine travel path must include moist sand with a particle size up to 2mm. The minimum depth of sand is 0.3m. If 0.3m is still penetrated by the machine lugs, it must be increased accordingly.

+ Lugged wheel rollers.

* Sand only.

• Note that: The test area is surrounded by the vertical projection of the microphone onto the ground.
• Measurements shall not be made under the following conditions:

+ When it is raining, i.e., rain, snow, or hail;

+ When the ground is covered with snow;

+ When the temperature is below -10°C or above +35°C;

+ When the wind speed exceeds 8m/s; for wind speeds exceeding 1m/s, a microphone windscreen shall be used and appropriate compensation for the effect of using the windscreen is permitted during calibration.

Role – importance of the Test Procedure for Determination of noise emitted by earth-moving machinery

The test procedure Determination of noise emitted by earth-moving machinery performed by DASM Institute helps provide useful information, meeting all practical needs of customers and businesses wishing to:

• Control noise, isolate the noise source, prevent noise, implement mitigation measures to avoid health and safety risks and avoid negative impacts on the surroundings.
• Measure the working environment and assign appropriate job tasks. Train workers exposed to a noisy environment to clearly understand the harmful effects of noise and safe working measures.
• Monitor equipment condition, early detect signs and causes of damage... to proactively maintain machinery.
• Material manufacturers, consulting – design... units of earth-moving machinery who want to achieve the purpose of noise reduction, sound absorption, sound insulation...; want to evaluate the effectiveness of noise reduction measures.
• Help control quality during the production process, optimize research and development of products and materials helping to reduce sound, noise, absorb sound, insulate sound... related to noise emitted by earth-moving machinery.
• Commercial businesses/consultants have a valid basis to propose and implement solutions prioritizing types of machinery, equipment, technical and technological initiatives suitable, capable of minimizing the impact of noise.
• Support legal dispute issues, lawsuits, forensic evaluation requests, measurement and analysis of environmental samples in case of environmental noise violations exceeding technical standards.

At the same time, DASM will conduct consulting and design work to create shape/structure/material solutions to efficiently, effectively, and cost-effectively adjust customer test samples (in case they do not meet standards).

If previously you still had some concerns, worries and had to spend many fees for similar activities abroad, now you just need to contact DASM.
