Legal requirement for boundary noise monitoring report singapore:

Boundary Noise Monitoring Singapore. As per Environmental Protection and Management (Boundary Noise Limits for Factory Premises) Regulations, it is mandatory for an occupier (factory license holder) of the workplace to measure the noise level at one’s workplace boundary in order to ensure that the noise level emanating from one’s premises does not exceed the limits prescribed by the law. Qsis Pte Ltd has on its rolls specialized personnel for providing noise measurement services. We cater to the needs of different clients and cover wide range of manufacturing industries, factories, workshops and petro-chemical industries.

Frequency of boundary noise monitoring:

The first step would be to do the initial (first) mandatory boundary noise measurement. The same is to be submitted along with Temporary Occupation Permit (TOP) application for the factory premises. The sound level measurement shall be done as per the direction given by the Director-General of National Environmental Agency.

The Director-General may require the owner or occupier of any factory premises, or any building or part thereof within any factory premises —
(a) to set up equipment to measure and record the level of noise emitted from his premises over such duration as may be directed by the Director-General; and
(b) to submit the records of the noise level readings including all relevant facts which may influence the values of the noise level readings (such as background noise).

The Director-General may also advise the occupier (factory license holder) to measure the noise level at some specific points/distance for specific duration due to the complaints received from the public or people inhabiting nearby premises. In some cases, the measured level may need to be adjusted keeping in consideration the background noises. Qsis Pte Ltd offers the best services to its clients by providing them fully skilled noise monitoring officer who holds a good degree of experience in distinguishing the noise level emitted by the premises and the background noises, and is adept in incorporating the findings into the boundary noise mapping report.

The sound level measurement points would be set at or about ground level running along the boundary of the factory premises (source of noise pollution) which faces any building on the affected premises; or if there is no building on the affected premises, it may be any part of the affected premises. In case of affected building being a part of the same factory premises which is being monitored, the measurement point to be set would be at any point in the range of 5 meter from the wall of the premises being monitored which is facing the affected premises. The sound pressure level would be measured at 10-15 meter interval for each measurement point along the boundary of the client premises. The sampling would be conducted on the day Period (7:00 AM ~ 7: 00 PM) whilst a 24-hour continuous sampling process will then be conducted at the potential highest Leq point where its corresponding Leq was recorded and referenced against NEA’s Permitted Boundary Noise Level.

Qsis Pte Ltd enrolls experienced and committed noise consultants whose job would include guiding the occupier (factory license holder) or owner of the premises in identifying and choosing the locations of measurement, interpreting measured readings with regard to the background noise, preparing and submitting the boundary noise monitoring report to National Environmental Agency (NEA).

Instrument to be used for boundary noise monitoring

As per the Director-General the measurements of noise levels shall be carried out with a sound level meter which complies with the standards specified in the International Electrotechnical Commission Publication 651 (Type 1) and Publication 804 (Type 1). Qsis Pte Ltd undertakes to use the calibrated sound level meter that is in conjunction with the legal requirement stated by the Authorities.

Legal limits for boundary noise level at boundary

Legally permissible noise level depends on the following variables:

  • The adjacent premises / affected premises
  • Noise sensitive premises
  • Residential premises
  • Commercial premises
  • According to the background noise level
  • Time of measurement (Different permissible noise levels set for different timings)

Qsis Pte Ltd ensures the provision of highly competent noise monitoring officer with a good experience in identifying the factors explained above and interpreting the readings while preparing the boundary noise measurement reports.

Submission of boundary noise monitoring report

As Qsis Pte Ltd is a registered noise monitoring company, it takes up full responsibility of submitting the noise monitoring report to its clients.

Requirement of ISO 14001:2015 – Environmental management systems

Boundary Noise monitoring, also known as Environmental Noise monitoring can be defined as any unsolicited and undesirable sound and it encompasses noise from industrial sources, transport sites as well as domestic premises. Environmental noise pollution may result in public annoyance and high noise levels may lead to hearing impairment.
In accordance with “The Planning Guidelines for Environmental Noise Limits and Control” published by Department of Environment, noise disturbance encompasses any sound which:

  • Jeopardizes the safety or health of human or animals; or
  • Hampers the activities of a reasonable person with normal sensory working; or
  • Endangers or encroaches upon personal or real property boundary; or
  • Crosses the existing ambient equivalent A-weighted sound level; or
  • Exceeds the sound level limits as specified in the Guidelines.

Measurement of noise levels is required for any of the following purposes:

  • Identifying and gauging the existing noise climate;
  • Appraising compliance to the noise limits for noise source(s) and/or project development;
  • Assessing environmental impact and potential community response.

Qsis Pte Ltd is offers accurate boundary noise level measurement services at carefully selected locations to help our clients:

  • Gauge the noise levels of a particular site in compliance with the Planning Guidelines for Environmental Noise Limits for planning purposes and EIA study
  • Assess the noise levels around an industrial site in accordance with the requirement of an ISO 14001 Environmental Management System
  • Identify disturbing sound frequencies and to measure the sound levels of a specific noise source or a combination of noise sources for the purposes of noise abatement.
