Material testing for the determination of noise emitted by water supply system equipment

The material testing for determination of sound emission from appliances and equipment used in water supply installations provides useful information to determine priority measures for noise control; monitor equipment condition, early detect signs and causes of damage... for proactive machinery maintenance; efficient production and product improvement...

Overview of the material testing for determination of sound emission from appliances and equipment used in water supply installations

Test name: Determination of sound emission from appliances and equipment used in water supply installations

Test methodology: ISO 3822-1:1999/Amd1:2008: Acoustics – Laboratory tests on noise emission from appliances and equipment used in water supply installations – Part 1: Method of measurement [1].

Performed at:

• On-site machinery location area.
• Reverberation room.

1. Objectives and test subjects

– Test objectives

Determine noise generated by the operation of appliances and equipment used in water supply installations.

– Test subjects

Appliances and equipment used in water supply installations for residential and industrial buildings.

2. Experimental procedure

Implementation steps:

• Fully equip with testing devices, microphones, and test samples.
• Conduct sample measurement.
• Process and report results.

3. Notes

• Laboratory testing

+ Encouraged to use multiple microphones (e.g., using 4 in figure 6)

+ The distance from the microphone to the wall should be no less than 1m.

• Field testing

+ Temperature, flow rate, and pressure of the water supply source must ensure conditions similar to laboratory testing.

+ The microphone is placed 1m away from the wall and at a height of 60cm (equivalent to the height of the ear position of a person affected by noise).

Role – importance of the material testing for determination of sound emission from appliances and equipment used in water supply installations

The material testing for determination of sound emission from appliances and equipment used in water supply installations conducted by the Institute of Acoustic Materials Development and Application helps provide useful information, meeting all practical needs of customers and enterprises wishing to:

• Control noise, prevent noise, isolate noise sources, implement mitigation measures to avoid health and safety risks and prevent negative impacts on the surroundings.
• Measure the working environment and assign appropriate tasks. Train workers exposed to a noisy environment to understand the hazards of noise and safe working practices.
• Monitor equipment condition, early detect signs and causes of damage... for proactive machinery maintenance.
• Material manufacturers, consulting – design units... of appliances and equipment used in water supply installations who want to achieve the purpose of noise reduction, sound insulation, sound absorption effectively...
• Help control quality during production, optimize research and development of products and materials helping in noise reduction, sound insulation, noise abatement, sound absorption... related to noise emitted by appliances and equipment used in water supply installations.
• Commercial/consulting enterprises have authentic grounds to propose and implement solutions prioritizing machinery, construction equipment, technical and technological initiatives that are capable of minimizing the impact of noise.

At the same time, DASM will conduct consulting and design work to create shape/structure/material solutions to streamline and efficiently adjust customer test samples at a cost-saving manner (in case standards are not yet met).

If previously you still had concerns, worries, and had to spend many costs for similar activities abroad, now you just need to contact DASM. The entire remaining process will be proactively implemented by us as a full package in the fastest time to complete the customer experience about us: DASM provides acoustic consulting services with truly superior quality, highly competitive prices in the industry along with thoughtful and dedicated customer care policies.
