Enviro-Acoustic Research
Noise: Define – Assess – Manage
Independent noise studies, ambient sound monitoring, noise propagation modelling and legal review for mining, industrial, transport, urban and renewable energy projects. We also assess blasting impacts and train professionals and authorities in environmental and occupational noise.
Reliable environmental noise data and clear, defensible reports that support environmental authorisation and public participation.
Noise measurement, modelling and management services aligned with South African legislation and international standards, now with blasting impact assessments and specialist training.
Review in terms of legislation and guidelines such as GNR154 of 1992, GNR320 of 2020 and SANS 10328:2008.
Monitoring at up to 10 locations simultaneously, for durations of up to four weeks. Why four weeks?
Statistical analysis of sound and noise level data to characterise the existing acoustic environment.
Compliance noise audits and professional measurement reports.
Defining noise sources and their sound power emission characteristics using actual measurements, existing databases, input from the engineering team or standards such as BS 5228-1:2009+A1:2014.
Predictive modelling of how noise travels from a project to surrounding receptors. Why accuracy pays
Noise pollution control and noise abatement programmes for operating facilities.
Design of noise control and mitigation measures to minimise and manage noise impacts.
For urban development, road and railway projects, industrial and mining activities and renewable energy projects, including 200 wind farms. When is one required?
Prediction of ground vibration (peak particle velocity), air overpressure and flyrock at nearby receptors, heritage structures and infrastructure, with practical mitigation for new and active operations. More on blasting

Plain-language articles on South African noise law, measurement and modelling, written from two decades of fieldwork and more than 500 noise studies.
What the GNR 320 Noise Protocol of 2020 requires of noise specialists in South Africa, what it changed, and why a silent Screening Tool is no exemption.
