How to accurately measure, identify, and locate noise indoors?

Indoor noise management is not only about regulating sound comfort; it is also a major safety concern. Therefore, it is essential to:

• Monitor sound levels in real time to prevent excessive disturbances
• Precisely identify the sources of noise to limit their impact
• Analyze the nature of sounds to detect any critical signals requiring immediate intervention

Ellona’s POD2 provides an advanced solution for monitoring, analyzing, and managing the indoor sound environment.

1. A central element for safety and indoor noise management

The POD2 ensures continuous monitoring in various environments:

• Offices & open spaces → Reduce acoustic stress and improve concentration
• Hospitals & healthcare facilities → Maintain calm and protect patients
• Industry & sensitive sites → Early detection of mechanical anomalies
• Public establishments (ERP) → Control sound levels to ensure comfort and safety

Unlike simple decibel measurements, the POD2 allows for the precise identification of the noise source and nature, enabling effective and targeted remediation based on the risk.

2. Identification of noise sources and nature for tailored remediation

The POD2 integrates artificial intelligence algorithms capable of:

• Identifying sound sources → Conversations, machines, alarms, ventilation, impacts…
• Qualifying the nature of the noise → Continuous, impulsive, mechanical, human, critical…
• Detecting critical signals → Explosion, gunfire, evacuation alarm, technical malfunction, etc. In sensitive environments, distinguishing between a common noise and a critical one is crucial. A simple impact (like a door slamming) will have a different implication than a gunshot, which would require immediate intervention by security teams.

With their advanced analysis capabilities, the POD2 allows for an appropriate and rapid response, avoiding misinterpretations and delays in dangerous situations.

3. Control strategy and tailored remediation

The effectiveness of an acoustic system relies not only on its ability to measure and identify noise but also on the relevance of the response implemented.

📌 Differentiation of threats and common disturbances

• A ventilation noise? Adjust the HVAC system parameters
• A peak of conversations in an open space? Adapt the layout or add partitions
• An abnormal noise from an industrial machine? Send an automatic maintenance alert
• A suspicious detonation noise? Trigger a security alert with a visual check

📌 Automation and integration into security protocols
The POD2 integrates with building management and security systems. In case of detecting a critical noise, an automatic alert can be sent to the relevant teams, avoiding intervention delays.

4. EllonaSoft: Intelligent acoustic data management

The POD2 is connected to the EllonaSoft platform, which allows:

• Monitor sound levels in real time
• Analyze sources and trends of noise
• Detect critical signals and trigger alerts
• Optimize remediation actions based on needs

With these advanced features, EllonaSoft simplifies noise disturbance management and enhances indoor safety.

Conclusion: A proactive and secure acoustic monitoring

The POD2 from Ellona is much more than a simple noise sensor:

• They provide continuous monitoring of sound environments
• They precisely identify the sources and nature of noises
• They differentiate between common disturbances and critical signals (gunfire, explosion, alarm, machine breakdown)
• They enable targeted and tailored remediation

Thanks to this approach, the POD2 contributes to the securing of indoor spaces, the optimization of working conditions, and the reduction of risks related to noise disturbances.
