pitt&sherry offer a broad spectrum of acoustic consultingservices including:

Noise Measurement

pitt&sherry operate a variety of Type 1 and 2 sound level meters

that meet AS1259 measurement precision specifications and therequirements of the National Measurement Act 1960. We havean in house Bruel & Kjaer 2260 Observer, and lease additionalmeters on an as-required basis, thereby ensuring that we alwayshave the right equipment for the job.

Noise measurement procedures take into account factors suchas the siting of instrumentation, other noise including extraneoussources, local meteorological conditions, observer location, sitedimensions and dominant (intrusive) characteristics of the sound– such as tonality, impulsiveness, modulation and low frequency.

Typical areas of application include:

Measurement and assessment of road traffic and railway noise•

Measurement of sound pressure levels at receptor premises in•relation to the measurement or assessment of noise emittedfrom commercial or industrial activity

Noise surveys relating to particular noise emitting activity –•including sporting and other entertainment activities

Background noise level measurement•

Air blast measurements in relation to extractive industry•blasting activities

Wind farms•

Noise emissions from discrete items of equipment.•

Noise Impact Studies

pitt&sherry personnel are able to undertake noise impactassessments of development proposals. These usually take thefollowing outline approach:

Identify potential impacts and the times during which these•impacts are likely

Undertake a site acoustic survey at relevant receptor•premises, to measure existing noise levels

Determine noise limits at each receptor site•

Predict, by numerical modelling, the noise levels arising•from the proposed development at the receptor premises andcompare with the limiting values

Investigate noise mitigation measures if required.•

Traffic Noise Modelling & Prediction

pitt&sherry use SoundPLAN to assess likely future traffic noisefrom road projects, and to design and evaluate noise mitigation

benefits from noise mounds and barriers.SoundPLAN is a leading international noise software modelthat is operated by over 3000 firms in more than 30 countries.SoundPLAN is a three dimensional graphics oriented programthat can present high quality graphical and tabular predictions ofnoise against a wide range of international noise standards.

Acoustic Condition Studies for Noise Sensitive Developments

An increased focus is being directed at controlling development ininappropriate areas – for example residential subdivision of landalready subject to high ambient noise – by restricting the extentof development or by requiring the provision of noise mitigationmeasures that will enable the relevant acoustic quality objectives

to be met.

pitt&sherry are able to assist developers and regulatoryauthorities to assess the likelihood that noise levels at proposednoise sensitive developments will exceed relevant acousticenvironmental quality objectives, and to develop appropriatemitigation measures if required.

Regulatory Compliance

pitt&sherry are able to undertake measurement and assessmentwork directed at establishing regulatory compliance for a rangeof activities and industries including:

Building construction and demolition sites•

Road construction and maintenance activity•

Blasting activity in the extractive industries•

Wind farms•

Sporting events•

Outdoor concerts•

Licensed premises•

Miscellaneous noise sources such as chainsaws, security•alarms, vegetation cutting equipment and the like.
