PROJECTS UNDER DEVELOPMENT
Mention to Projects under development this quarter
Underwater Noise Assessment and Modeling Training for the National Environmental Licensing Authority (ANLA) of Colombia (Theoretical/practical course).
Project financed by the IDB that will provide professionals working in the Colombian Authority with the competence required for the supervision and granting of environmental permits in the area of underwater noise / Training integrates the delivery of theoretical background, regulatory scopes, description of marine fauna and noise fronts, practical exercises and learning to use dBSea specialty software.
Design and Implementation of Acoustic Solutions in the Salmon Industry.
Project that implements in two industrial plants the first stage of a plan of noise control measures in the scope of both Prexor Protocol and DS38 / It considers the application of acoustic attenuators type Splitter, cylinder type silencer, double glazing type DVH and acoustic enclosures.
Evaluation of underwater noise from a project located in the XII Region associated with green hydrogen production.
The consultancy includes underwater background noise measurement campaign, characterization of noise sources, development of a three-dimensional model of sound propagation that integrates the influence of bathymetry, water temperature and salinity, preparation of noise maps, determination of the extension of the area of influence of the project, evaluation of behavioral and physiological effects on marine fauna (low frequency cetaceans, medium frequency cetaceans, high frequency cetaceans, phocid pinnipeds, otarid pinnipeds, turtles and fish), according to the SEA Guide “Evaluation Criteria in the SEIA: Prediction and evaluation of underwater noise impacts.
Design and Implementation of Acoustic Solutions in the Food Supplements Industry
Project that implements in industrial plant noise control measures within the scope of the Prexor Protocol / It considers the application of acoustic attenuator Splitter type, mobile acoustic screen and acoustic conditioning of worm screw.
We observe on a daily basis how to apply continuous improvement in our quality standards and staff competencies.
PROSAC SPA performs baseline surveys, characterization of noise sources, prediction and evaluation of underwater noise impact and definition of the area of influence, according to the most updated technical criteria defined by the Ministry of Environment and the Environmental Assessment Service.
PROSAC SpA offers a comprehensive environmental noise assessment service, for the verification of compliance with national regulations D.S. 38/11 MMA and international reference standards. Inspection of the area around projects with drone flight.
NOISE CONTROL ENGINEERING
PROSAC SpA carries out integral turnkey projects, considering environmental and labor compliance, including the necessary noise measurements and more. Inspection of the area around projects with drone flight.
PROSAC SpA performs this projection through the elaboration of noise maps with advanced B&K Predictor Lim-A software, modeling the exclusive sound contribution of noise sources and fronts.
The main objective of the PREXOR protocol is to reduce the incidence and prevalence of occupational hearing loss, which in simple words is to reduce the number of workers with hearing loss.
NOISE AND VIBRATION MEASUREMENT
PROSAC SpA thanks to its experience in acoustic noise and vibration measurement services, which allows us to comply with national and international standards and regulations.
WE HAVE ALREADY WORKED WITH
COMPANIES SUCH AS
We present a series of acoustic solutions elaborated with a general design, which can be requested to our company and modified according to the client’s needs, either in size, materiality, assembly, etc.
SOME OF THE PROJECTS
IN ACOUSTIC ENGINEERING
These are some of the projects we have developed
together with our team of professionals.
Soundproofing of electrical room in food industry company
Our engineering team advised a food industry company located in the Libertador Bernardo O’higgins Region, to reduce the sound pressure levels of two back-up electrical rooms, which had generators that generated oil-based energy.
The general solutions ranged from the incorporation of splitter-type silencers in the air intake and discharge of the rooms, improvement of the gas exhaust silencers, conditioning of doors and gates and the internal lining of the rooms.
Acoustic cabin oriented to control cabin and sound rest in accordance with PREXOR protocol requirements in the boiler room area. Complete consulting, design, construction and implementation of an industrial plant in the Tenth Region. Noise level differential outside and inside the cabin resulted in a differential of 20.8 dBA.
Acoustic barrier in electric company
An electrical company located in the Biobío Region requested the services of PROSAC SpA to design and build an acoustic barrier, in this case 78 meters long and 6.5 meters high, in order to reduce the noise levels affecting neighboring companies.
Noise barrier port company
PROSAC SpA designed and built an acoustic barrier for a port company in the Los Rios Region, 11 meters high with an extension of 86 meters, in order to reduce the environmental noise levels that affected neighbors of the client company. For this same work center, the alarm system for front loader type heavy machinery was modified, reducing the sound pressure level emitted by the warning sirens when backing up, contributing to a reduction in noise both in the environment and in the workplace.
Noise control in forced air injection system
Our company advised in the design, construction and assembly of an acoustic Splitter type device in an air injection system arranged in a production line in a salmonid food industry. Results obtained indicate a noise attenuation from 102.8 dBA to 75.2 dBA. dBA with a resulting noise abatement differential of 27.6 dBA.
Scenario that derived in the annulment of the relevance of the noise front in the location of the community receptor points.

Ebook: Key aspects for understanding PREXOR
As professionals in noise prevention, it is important that we are aware of the current regulations that a company must adhere to in order not to be sanctioned due to the damage that can be caused by poor noise management.
In this “DIGITAL BOOK” you will find all the information you need to know about the PREXOR application.
PROSAC is a team whose vision is to cover in an integral way the requirements of acoustic engineering.
