Noise Survey Services
Noise Monitoring & Survey Onboard Marine Vessels refers to the process of measuring and evaluating noise levels in different areas of a ship to ensure they remain within safe and acceptable limits. This is essential for protecting the health and hearing of crew members, especially in high-noise zones like engine rooms, machinery spaces, and deck areas during operations.
Environment Noise Survey Services
Assetconditionmonitoring.com offers professional noise monitoring services to identify high-risk areas with excessive sound levels in industrial and marine environments. Using precision instruments, we assess noise exposure, especially where workers must speak loudly to communicate at close distances. Common zones include ship decks, plant floors, and airport operations. These surveys help implement effective safety measures to protect workers and ensure compliance. As part of our marine services, we also provide condition monitoring to detect issues early and extend equipment life.
What is Environmental and occupational noise
Environmental noise and occupational noise serve different contexts and are assessed using distinct standards due to their varying sources, exposure patterns, and health impacts.
Environmental noise refers to unwanted or disturbing sound that originates from sources in the external environment, particularly around residential or public areas. Common sources include road traffic, railways, aircraft, and industrial facilities such as factories or construction sites. This type of noise is generally lower in intensity but can affect large populations over extended periods. It is often considered a public health concern, contributing to stress, sleep disturbance, and reduced quality of life. Environmental noise is commonly regulated by local environmental agencies and measured in terms of its impact on communities rather than individual exposure.
In contrast, occupational noise is the sound experienced in the workplace as a result of machinery, tools, engines, or industrial processes. While some level of noise is considered part of many working environments, prolonged or excessive exposure can pose serious risks to hearing and overall worker health. Unlike environmental noise, occupational noise is measured against specific exposure limits defined by occupational health and safety regulations (e.g., OSHA, HSE, or ISO standards). Employers are required to assess noise levels, provide protective equipment, and implement controls where necessary to protect workers from hearing loss and other health risks.

Types of Noise Measurements
For a noise survey, different types of noise measurements are carried out, depending on the requirement, for instance, occupational, environmental, or community noise. A few are listed below:
Spot Noise Measurements
It captures the noise level at a specific location and moment in time.
Continuous Noise Measurements
Records noise levels continuously over a set duration to evaluate variations.
Equivalent Continuous Noise Level
Represents the average noise energy over the measuring period.
Maximum and Peak Noise Levels
The highest sound level recorded during the survey.
Statistical Noise Levels
Describe noise exceeded for 10, 50, and 90 percent of the time, denoting fluctuating and background levels.
Time-Weighted Average Noise (TWA)
The average exposure of a person to noise during a standard work shift.
Octave Band or Frequency Analysis
Breaks noise into frequency bands to find dominant sources and plan control measures.
Advantages Of Environmental Noise Surveys and Monitoring
Environmental noise is the unwanted outdoor sound that affects a specific area and its surrounding locality. It generally occurs through human activities and includes industrial noises such as welding, hammering, drilling, and grinding, transportation noises, domestic noises, etc.

Why Choose Us?
At Assetconditionmonitoring.com, we utilize advanced sound level meters such as the Optimus+ Red by Cirrus Research PLC to carry out both continuous and short-term noise assessments. These high-performance instruments are specifically designed for accurate occupational noise monitoring, helping us capture precise data in various workplace environments. Sound itself is a variation in air pressure, measured in decibels (dB), ranging from 0 dB—the softest sound the average human ear can detect—to levels above 120 dB, which are considered dangerous. In industrial settings, noise levels can often rise significantly, posing serious risks to workers if not properly managed.
