Case Studies

Workplace Noise Exposure

A recent study completed by the engineering group at Akoustik entailed a complete noise exposure assessment of a major Windsor industrial facility. The purpose of this exposure assessment was to conduct acoustical measurements for the identified job classifications and areas/rooms having a potential of risk exposure and post-analysis of said acquired measurement data. As part of the assessment, any noise control requirements necessary to allow the client to meet the Ontario guidelines and...

Environmental Compliance Approval (ECA)

The engineering team at Akoustik recently completed an environmental noise impact assessment as part of an Environmental Compliance Approval (ECA) application as required by the Ministry of the Environment and Climate Change (MOECC). The assessment was prepared for a proposed cogeneration and pellet mill project in northern Ontario. The proposed construction plan of the facility includes a green biomass fuelled electrical power and heat 4.3 megawatts of electricity (MWe) cogeneration plant and...

Noise Source Indentification

Akoustik Engineering Limited performed a thorough noise source identification (NSI) analysis for Gold Corp Canada Ltd. to identify and control significant noise sources of 785B haul trucks. The purpose of the NSI analysis is to identify the significant noise contributors and recommend abatement solutions to reduce the overall sound power level of the 785B haul trucks and reduce the environmental noise impact. NSI is a highly technical analysis that can accurately identify significant noise...

Vibration Assessment of Loaders for Windsor Salt

In an effort to ensure the health and safety of their employees, Windsor Salt brought in the engineering team at Akoustik Engineering to assess the whole body vibration (WBV) health risks as an outcome of continued operation of the loader vehicles in the underground mine. The associated risks of WBV include short-term effects such as nausea, headache and fatigue, as well as long terms effects including difficulties to move, disability, impairment and psychological problems. Two types of...

Acoustical Study of Downtown Minneapolis

Selection of Outdoor Warning Siren

The engineering team at Akoustik recently completed a large-scale acoustical study of the downtown area of the City of Minneapolis for the hardware selection and placement of an outdoor warning siren system. This acoustic study had two primary goals. The first was to determine the minimum required sound pressure level (SPL) that the siren would need to produce throughout the study area based of the present predicted worst case ambient sound pressure levels. In order to do this, a model of the...
