TRACK RECORD

Featured projects

Over more than 15 years we have delivered 900 projects, 125 of them approved by the SEIA, always with a single team of Acoustic Civil Engineers and no outsourced stages. These are some that best show our experience.

Regulatory authorship: we work for the regulator

We have prepared technical background for the Ministry of the Environment on the noise standards and methodologies now in force in Chile. It’s the same experience we use to anticipate what environmental review will require of you.

Acoustic characterization of wind farmsMinistry of the Environment & Ministry of Energy · 2017–2018A study for the MMA that characterized the noise of six operating wind farms in Chile, combining discrete and 14-day continuous measurement campaigns with sound power level measurements of the turbines. The work proposed criteria for assessing wind-farm noise.6 wind farms14 days of continuous measurement3 turbines per farm Background data for the review of D.S. N°38/11Ministry of the Environment · 2019–2020Baseline study for the modernization of Chile’s fixed-source noise standard. Territorial planning instruments from 116 municipalities —home to 80% of the national population— were systematized, noise from regulated sources was measured against four international reference standards, and 50 SEIA projects with environmental follow-up were analyzed.116 municipalities80% of the population50 SEIA projects~177,900 km² Wind-farm noise measurement protocolMinistry of the Environment · 2025Generation of background data for an official protocol to measure and process wind-farm noise levels. Using Class 1 instrumentation and two-week continuous campaigns at operating wind farms, technical criteria were developed that robustly correlated noise with wind speed at every point assessed.2 operating wind farmsClass 1 instrumentation4 technical criteriar² ≥ 0.6 at all 6 points Route 5 North–South Noise MapMinistry of the Environment · 2018–2019Development of the noise map for the concessioned stretch of Route 5 North/South —Chile’s main land transport artery— for the Ministry of the Environment. The study modeled traffic noise along 2,150 km across 101 municipalities, analyzed 13 priority areas in detail, and evaluated mitigation measures such as noise barriers, low-noise pavements and façade insulation.2,150 km of highway101 municipalities106 noise measurements~1.8 million people Noise assessment in Coronel (PRAS)Ministry of the Environment · 2015Noise-level assessment under the Environmental and Social Recovery Program.54.9 km² assessed~80 noise sources catalogued53 measurement points6 project phases Noise update in the commune of CoronelMinistry of the Environment · 2023–2025Assessment of exposure and mitigation of vehicular and rail noise in the commune.6 work streams21 traffic cameras (24 h)2 online monitoring stations89,573 people assessed

Major projects in the SEIA

Noise and vibration studies for the EIA and DIA of energy, port and transport-infrastructure projects.

Junquillos Wind FarmWSP · 2022–2025Noise and vibration impact studies for the EIA of a 63-turbine wind farm in the Biobío Region. The noise baseline was characterised with 8 continuous background-noise measurement points over 14 days each, complemented by discrete measurements.63 wind turbines238 receptors (noise)8 continuous points · 14 days192 receptors (vibration)CadnaA / ISO 9613 San Antonio Outer PortJaime Illanes y Asociados · 2024–2026Acústica Austral was brought in for the Complementary Addendum to the EIA —after 262 authority observations on noise and vibration had accumulated in the prior review— and reworked both studies for one of the largest port projects ever approved in SEIA history. The assessment integrated five noise source types (port, road and rail traffic, blasting and helicopters), six reference standards and an extensive baseline measurement campaign.Among the largest approved in the SEIA262 observations resolved41 discrete + 23 continuous 24 h (noise)53 vibration measurements5 source types · FTA · AS 2187-2 Antofagasta Region Rail TransportEmpresa de Transporte Ferroviario S.A. · 2022–2023Acústica Austral reworked the noise and vibration studies for this Environmental Impact Statement (DIA) —previously rejected for processing by the SEIA over acoustic observations— and the project secured admission and subsequent approval.

What our clients say

“Working with Acústica Austral has been an excellent experience. We have been working together for more than 10 years, and we highlight their professionalism, fast response times and the high technical standard of their noise and vibration modelling, which has been key support for the development of our Environmental Impact Statements (DIA).”

“We have been working with them for a year now and the service has been excellent. They stand out for their technical knowledge, commitment, proactivity, responsiveness and flexibility: everything you expect when you hire an expert consultancy.”

Bernardino Camousseigt

Environment and Permits Coordinator · Enel Green Power & Thermal Generation Chile

August 4, 2026

“Acústica Austral has been a strategic partner for AES Chile in understanding and adapting to the regulatory changes affecting environmental noise and wind farms. Their technical capability, data-driven analysis and contribution to the development of compliance criteria and protocols have enabled us to anticipate regulatory risks and strengthen the environmental management of our wind generation assets.”

Cristian Araneda

Corporate Manager, Environmental Operations and Strategy · AES Andes

“We have had an excellent experience with the Acústica Austral team. They have shown a high level of technical capability, particularly on some complex projects where they delivered highly appropriate solutions that were subsequently validated by the authority. Another very relevant aspect is their courteous approach and their good handling of relationships with project proponents and clients.”
