Monitoring & Measurement
Noise and vibration measurement that shows clearly how your site affects its neighbours and workforce, and what to do about it.
Fewer noise complaints and clear evidence for authorities
Noise monitoring is the measurement of sound levels — and, where relevant, ground-borne vibration — at a site boundary, at nearby sensitive receptors or in the workplace, to assess impacts and compliance with applicable limits. It uses calibrated sound level meters or continuous monitoring terminals and reports indicators such as equivalent continuous level (LAeq), maximum levels and frequency content.
Noise is a common source of complaints about construction sites, industrial plants, power and utility facilities, entertainment venues and transport infrastructure. As development in Saudi Arabia brings industrial, commercial and residential uses closer together, authorities, project owners and communities pay more attention to noise. Environmental permits, EIA approvals and construction environmental management plans often require baseline noise data, limits at site boundaries or receptors, and monitoring during construction and operation.
Our noise monitoring service covers the main types of environmental and workplace noise assessment. We carry out baseline surveys before a project starts, monitor construction noise and vibration near homes, schools, hospitals and sensitive structures, and measure operational and boundary noise from plant and equipment. For long or sensitive projects we install continuous noise monitoring terminals with remote data access and alerts. We also conduct occupational noise surveys to identify high-noise areas and support hearing conservation measures. All measurements use calibrated instruments, with meteorological conditions and noise sources documented.
Measured data on its own rarely solves a noise problem. Our reports interpret results against applicable limits and baseline conditions, identify the dominant sources and recommend practical mitigation such as scheduling changes, equipment selection, enclosures, barriers or operating procedures. This helps project managers respond to complaints with evidence, demonstrate compliance to authorities and plan control measures before they become costly. Noise monitoring can run as a stand-alone survey or as part of a wider environmental monitoring programme.
You may need this service when:
Measurement of existing noise levels at the site and nearby receptors before a project starts, covering day and night periods as required.
Monitoring of noise and vibration from construction activities near sensitive receptors and structures, with trigger levels and documented responses.
Measurement of noise from operating plant and equipment at site boundaries and receptors, with identification of dominant sources and their contribution.
Installation and operation of unattended monitoring terminals with remote data access, alerts and, where needed, audio recording to identify noise events.
Area and personal noise measurements in workplaces to map high-noise zones and support hearing protection and engineering controls.
Reports interpreting results against applicable limits and baselines, with practical mitigation options for sources, transmission paths and operating practices.
We review the project, noise sources, receptors, applicable limits and permit or specification requirements to define the survey type and scope.
We select measurement locations, periods, indicators and instruments, and agree the plan and any trigger levels with your team.
We carry out attended surveys or install continuous terminals, record weather and sources, and check calibration before and after measurement.
We process data, exclude affected periods, identify dominant sources and compare results with limits and baseline levels.
We issue reports with findings and practical mitigation recommendations, and review priorities with your project or operations team.

Requirements vary by activity, location and permit conditions. We confirm the applicable requirements for your project at the start of every engagement.
Environmental noise monitoring measures sound levels at site boundaries and at nearby receptors such as homes, schools or hospitals, to assess the effect of a site on its surroundings. Occupational noise monitoring measures noise in the workplace to assess employee exposure and support hearing protection. The methods, indicators and applicable limits differ, so the scope should be defined clearly before the survey starts.
It depends on the purpose. A baseline survey usually needs measurements covering representative day and night periods, and sometimes weekdays and weekends. Construction and operational monitoring may continue for the duration of the activity. Short attended measurements can identify sources, while continuous terminals capture variation over time. We propose a duration that fits your permit, project specification and the variability of noise at the site.
Yes. Construction activities such as piling, compaction, demolition and blasting can cause ground-borne vibration affecting nearby buildings, sensitive equipment or occupants. We measure vibration at agreed locations, set trigger levels where required and report results together with noise data, so project teams can manage both impacts with one monitoring arrangement.
Continuous terminals record noise levels throughout the day and night, and can send alerts and capture short audio recordings when levels rise. When a complaint is received, the data shows what levels occurred at the relevant time and, often, what caused them. This allows a factual response and helps distinguish site noise from other sources such as traffic or neighbouring activities.
Recommendations depend on the source and the receptor. They may include rescheduling noisy activities, selecting quieter equipment, maintaining silencers, relocating plant, installing enclosures or acoustic barriers, and adjusting operating procedures. We prioritise measures by expected effect and practicality, so your team can decide where to act first.
