Each sector has specific requirements, noise sources and challenges. The OTOH technology adapts to these particularities to generate relevant information for the management of each operation.

Traceability solution and data for incorporators and builders that need to act quickly, manage complaints and comply with the EIV.

Continuous monitoring for control and management of noise for shows, festivals and licensed spaces.

Support for urban noise management integrated with smart city solutions.

Continuous monitoring of operations and their impacts on the surrounding communities.

Continuous support for PGR, labor demands and related assessments to NR-1, NR-15 and PPP.

Operating sectors

Monitoring adapted to the reality of each operation

Construction noise management to reduce conflicts with the neighborhood

Real-time noise alerts

Strategic data for noise monitoring

Noise monitoring for environmental compliance

Continuous registration for noise management

Cases of use

When a complaint arrives, I extract the report and have a plausible justification quickly.

(...) very good to be able to analyze (data), make decisions with real basis.

The service was fast, the evaluation and visit were also everything great for us.

Real cases of noise management with continuous data

Companies that achieved these results

Monitor your operation 24 hours a day, automatically identify the main sources of noise and have the complete record quickly to verify compliance, investigate incidents and support technical decisions.

Continuous Sound Monitoring · IoT + AI

With specialized support and a simple implementation, transform the noise of your operation into information that guides decisions.

The contract starts with a diagnostic meeting, which aligns the scope of the monitoring with your operation.

The contract is a recurring service and includes the necessary investment for implementation and use of the system.

Just a bivolt power point and 15 minutes per station to implement the system and have acoustic data.

The monitoring stations have independent connectivity, without the need for local network.

The monitoring data is encrypted, and the system does not record audio by default.

The monitoring stations are autonomous, do not need local network.

How it works

Contract according to your operation

Quick implementation and real-time data

Noise management with privacy and security

The OTOH technical team performs an operation diagnosis to define the correct number and placement of sensors.
This sizing takes into account factors such as installation, distribution of sound sources, and critical monitoring points.

The OTOH technical team works with your team to assess the needs and characteristics of each requirement to define the most appropriate monitoring period.
The length is fully flexible and can be adjusted to the needs of each operation, ranging from short-term projects to long-term, continuous monitoring.

OTOH monitors, identifies the source, and documents noise behavior. 
With this knowledge in hand, your team can take proactive steps to reduce noise by rescheduling, relocating sources, and managing suppliers.
Designing and installing physical noise control solutions, such as acoustic barriers, insulation, or machine enclosures, is not within OTOH's scope. In these cases, an acoustic consultancy can decide and prioritize interventions more accurately and assess their efficiency after implementation.

To implement the system, you only need to provide an electrical network and the location where the sensors will be installed. The system is, by default, simple, and the team can study alternatives if the project requires any specific needs.

The OTOH digital platform can be accessed from any device without the need to install an app or software.
During the diagnostic meeting, we define who on your team will have access to the data, as well as the need to receive alerts and your preferred notification channel.

The OTOH system does not record audio by default.
The data is encrypted and respects both company and personal privacy.
Audio sample collection is an exceptional procedure, aimed exclusively at identifying customized sound sources, and is only carried out with prior and explicit authorization defined in the diagnostic meeting.

To ensure that the commercial proposal is tailored to your needs, the first step is to schedule a diagnostic meeting. This way, our technical and commercial team can assess your scenario, allowing the scope design to be aligned with your requirements.
Only then can we present the investment needed for implementation and use of the system, ensuring the scope matches exactly what you need.

The OTOH system includes intelligent monitoring, the data management platform, and the use of sensors on a lending basis.
Our model is a service provision, in which the sensors remain under our technical responsibility and management.

Frequently Asked Questions

Check the record of the period and verify exactly what happened, even days after the event. Source identification allows responding with technical evidence.

Differentiate the monitored operation from external noise and direct actions to the correct cause.

Each event is associated with its main sound source.

Clarify what happened with continuously recorded data.

The history supports the resolution of conflicts, the relationship with the neighborhood and the verification of compliance.

The OTOH identifies the source of the noise, when it occurred and how long it lasted. With this information, your team acts on the correct cause, differentiates operation events from external sources and responds to complaints with evidence.

Why Source Identification

But it's necessary to understand the source of the noise to act
