Altissimo Consulting

Acoustics and environmental engineers

We specialise in environmental acoustics and work with government agencies, district councils, and private clients to provide expert advice on noise and vibration issues. Our experienced engineers partner with clients to understand their specific needs and provide clear, practical advice to assist with their decision making.

Below, you can find more details about our areas of expertise, and you can view a portfolio of our work.

Assessment and reporting

Most development requires an assessment of environmental effects under the Resource Management Act. We work with private and public clients, as well as councils, to identify the relevant issues for consent and designation applications.

Noise can be difficult to explain at times, and many people's eyes glaze over at the mere sound of 'dBs'. We specialise in performing robust technical assessments, yet presenting our findings in plain English, strengthened by clear graphics.

We have experience in developing and presenting expert evidence for hearings.

Road-traffic noise

Our experience with Waka Kotahi and other road controlling authorities is extensive. We work closely with the national office providing services which influence local and national policy decisions. We have extensive experience in providing the full range of road-traffic noise assessment, reporting, and mitigation services for individual roading projects.

Some examples of roading projects our team has worked on:


Assistance with acoustics guides (NZS 6806, construction, measurement, noise mapping)


Programme Business Case (Nelson Southern Links)


Consenting (Ōtaki to North of Levin, Peka Peka to North Ōtaki, Russley Road 4-laning)


Detailed design / construction (Transmission Gully, Tauranga Eastern Link, Cambridge Bypass)


Close Proximity Measurement (CPX) of road surface noise


We work closely with contractors to produce Construction Noise and Vibration Management Plans that actually work for them. We aim to develop management plans that are much more than a simple document produced for compliance purposes and collect dust in the corner.

We specialise in developing tools that allow clients to take control of their noise and vibration management. This saves the client money, improves compliance, and supports good relationships with affected stakeholders.

Custom instrumentation and remote monitoring

We are experienced at developing measurement solutions for noise and vibration monitoring using the National Instruments platform and various sensors.

We have also developed web platforms to allow our clients and/or the public to see results

Some examples of roading projects we have worked on:


Close Proximity Measurement (CPX) trailer for measurement of road surface noise and associated parameters (see case study).


Canterbury Acoustics Testing Service reverberation room.


Web dashboard for Transpower to view tonality from conductors.


Long term noise monitoring and web dashboard for community engagement for roading projects (Waka Kotahi).
