Air Quality & Acoustics

Air Quality & Acoustics

We offer a wide array of air quality and acoustic measurement services for Ambient/outdoor and indoor locations. Our experience cuts across numerous project types not limited to compliance monitoring, Environmental Assessments using a combination of hand-held meters and continuous monitoring systems (passive monitors using diffusion tubes and or IoT-based active monitors using Air Quality Monitoring Systems AQMS).

Some notable indoor and outdoor air quality parameters that we specialize in measuring and assessing include but not limited to:

Ambient Air Quality

TPI has the expertise and experience to help you navigate the complex world of air quality regulations and ensure compliance with local and international standards.

Whether you are a small business looking to improve your indoor air quality or a large facility seeking to quantify your emissions, we have the solutions you need.


Ambient air quality parameters are:

  • Ozone (O3)
  • Nitrous Oxides (NO, NO2)
  • Sulfur Dioxide (SO2)
  • Carbon Monoxide (CO)
  • Particulate Matter (PM2.5, PM10)
  • Ammonia (NH3)
  • Carbon Dioxide (CO2)
  • Methane (CH4)
  • Hydrogen Sulphide (CO2)
  • Volatile Organic Compounds (VOCs)

It’s important to note that the specific air quality parameters that an environmental consulting firm measures and assesses may vary depending on the specific needs and goals of the client, as well as local and international regulations.

Indoor Air Quality

Maintaining good quality air within residential or official buildings is an essential step toward the well-being of its occupants. We offer monitoring and certification for IAQ with extremely stringent measures using state-of-the-art and professional-grade calibrated instruments with vast knowledge and experience to interpret results, review and offer recommendations where necessary. Utilizing IoT, TPI can design and implement for your organization a continuous IAQ system with the installation of sensors around areas of concern.


Some of the parameters we measure include:

  • Carbon monoxide, 
  • Volatile Organic Compounds, 
  • Particulates, 
  • Formaldehyde,
Acoustics (Noise & Vibration)

Noise from industrial and construction activities can be disruptive to nearby residents and can have a negative impact on their quality of life. 

Our statistical noise assessment services in line with BS 4142, focus on Ln (A-weighted equivalent continuous sound level) which is a measure of the average sound level over a specific period. 

Our services include:

  • Measurement of Ln levels at sensitive receptors (e.g. residential buildings, traffic)
  • Identification of sources of noise
  • Statistical analysis of Ln data to predict future noise levels and identify potential problem areas
  • Recommendation of mitigation strategies based on statistical analysis
  • Implementation and monitoring of noise control measures

Stack Emission Monitoring

Stack emissions from industrial facilities can have a significant impact on air quality and human health. TPI specializes in providing comprehensive stack emission monitoring services to help industrial facilities stay compliant with regulations and minimize negative impacts on the environment. Our team of experts has extensive experience in conducting stack emission assessments and providing solutions to mitigate any potential negative impacts.

Our stack emission monitoring services include:

  • Measurement of pollutants in stack emissions using state-of-the-art analytical equipment such as continuous emissions monitoring systems (CEMS) and extractive sampling systems.
  • Identification of sources of pollutants within industrial facilities
  • Recommendation of appropriate mitigation strategies, including design of emission control measures.

By choosing our stack emission monitoring services, industrial facilities can have peace of mind knowing that they are operating in an environmentally responsible manner. Plus, our stack emission monitoring services can also help industrial facilities identify ways to improve their operations and reduce costs.

Modeling Services:

At TPI, we specialize in the fate and transport of contaminants in the air, surface water, and groundwater. We are dedicated to helping clients understand and manage the impact of pollutants on the environment before they occur. Our team of scientists has extensive industry knowledge and experience in identifying and assessing the impact of pollutants on the environment.

Our modeling services include the use of advanced computer modeling techniques to predict the fate and transport of contaminants in the air, surface water, and groundwater, and to predict the impact or evaluate the effectiveness of different remediation strategies. We also use GIS mapping and 3D visualization tools to create detailed images of subsurface conditions and to identify areas of concern.
