Noise & Light Testing
On-site measurement of workplace and ambient noise levels and workplace illumination against CPCB, Factories Act and OSHA limits, so your facility stays within statutory limits and audit-ready.
What is noise and light testing?
Noise and light testing measures ambient and peak sound levels using calibrated sound level meters and dosimeters, and workplace illumination using lux meters, then benchmarks both against CPCB limits and green-building thresholds. Over 1.1 billion people in India face hearing damage risk from high workplace decibel levels, and as a result CPCB mandates noise level testing at least once a year for industrial and commercial spaces. Workplace lighting carries its own risk: inadequate or glare-heavy illumination is both a safety hazard and a common gap flagged during LEED and WELL certification reviews.
Equinox Labs surveys ambient and peak noise levels using calibrated sound level meters and dosimeters, and workplace illumination using lux meters, benchmarked against CPCB day/night limits and green-building thresholds. Testing is carried out at NABL-accredited (ISO/IEC 17025) standards across office floors, factory zones and outdoor boundaries, trusted by 95,000+ clients nationwide. It's one part of our broader environmental testing services.
How Noise and Lighting Conditions Affect the Workplace
Noise and lighting conditions can influence comfort, concentration and safety in the workplace. Assessing sound levels and illumination can help organisations identify areas that may need further investigation or improvement.
- Permanent Hearing Loss: from unsafe sound exposure levels without adequate protection.
- Reduced Concentration: sustained high noise cuts worker focus and workplace wellness.
- Eye Strain & Headaches: from inadequate brightness or harsh glare at workstations.
- Reduced Alertness: poor lighting drags down focus and task performance.
- Task Performance Errors: precision-based work suffers most under inadequate lighting.
- Mood & Sleep Disruption: light flicker and UV imbalance affect mood and sleep quality.
Noise and Lighting Assessments for Different Facility Needs
Assess workplace sound levels and illumination through a testing scope tailored to your facility and assessment objectives.
Ambient & Zone-Wise Noise Monitoring
Sound level readings across departments and boundary points during working hours.
Peak Sound Event & Dosimeter Testing
Continuous exposure monitoring and high-decibel spike tracking near high-risk equipment.
Illumination (Lux) Surveys
Lux-meter readings across workstations, walkways and production areas.
Glare, Flicker & Emergency Lighting Checks
Glare, contrast and UV exposure assessment, plus emergency lighting and exit illumination verification.
Machine & Equipment-Specific Noise Testing
Source-level readings on individual machines to pinpoint which equipment drives a zone over limit.
Bundled Noise + Light Compliance Audits
Both surveys run in the same site visit, saving time and cost over booking them separately.

Noise / Light Testing FAQs
Noise and light testing assesses sound levels and workplace illumination in selected areas of a facility. Depending on the agreed scope, noise measurements may include equivalent continuous sound levels (Leq), peak readings and exposure monitoring. Lighting assessments may include illumination in lux and selected lighting-quality parameters.
Noise assessment requirements depend on the facility, the purpose of monitoring and the applicable legal or regulatory provisions. India's Noise Pollution (Regulation and Control) Rules, 2000, specify ambient noise standards for industrial, commercial, residential and silence-zone areas. Confirm the requirements applicable to your facility before scheduling testing.
Under India's Noise Pollution (Regulation and Control) Rules, 2000, ambient noise limits are specified by area category and time of day. Industrial areas have limits of 75 dB(A) Leq during the day and 70 dB(A) Leq at night. Commercial areas have limits of 65 dB(A) Leq during the day and 55 dB(A) Leq at night. Workplace exposure criteria may differ from these ambient noise standards.
Noise and lighting measurements may support relevant green-building assessments or documentation where the applicable certification criteria require them. The required parameters, methods and documentation depend on the rating system and project requirements. Confirm the specific scope before booking.
The potential risk from noise depends on its level, duration and exposure pattern. Occupational noise assessment should use the applicable exposure criteria and suitable measurement methods. Where measurements indicate a potential risk, further assessment and appropriate control measures may be needed.
Emergency lighting assessment may be available depending on the service scope. Confirm whether your requirement involves illumination measurements, functional testing, exit-lighting checks or a combination of these activities.
Yes. Equinox Labs can discuss a combined noise and lighting assessment for your facility, subject to service availability and the agreed testing scope. Combining the assessments may help coordinate the site visit.
Reports are typically delivered within 3–5 working days after the site visit. Confirm the timeline for your facility, the scope of measurements and any additional reporting requirements.
The price depends on factors such as facility size, the number of areas to be assessed, the testing scope, required monitoring duration and site location. Contact Equinox Labs with your requirements to request a quotation.
