Cloud-connected hearing protection with real-time noise dosimetry and speech passthrough for construction sites.

FocusLite 2.0 is active-passive hearing protection (SNR 29dB, capped output 82–83dB) paired with cloud dosimetry (SmartHub/Peak platform). It addresses two construction compliance gaps: passive PPE that masks site warnings, and fragmented/sampled noise exposure data. Deployed across 7 UK Tier-1 contractors and TfL.

FocusLite 2.0 addresses two distinct failures in conventional site hearing protection: passive PPE that blocks hazard warnings alongside harmful noise, and fragmented audiometric sampling that leaves compliance gaps between measurements. The device delivers active speech passthrough alongside SNR 29dB attenuation capped at 82–83dB, with continuous dosimetry logged to the SmartHub cloud platform — solving both problems in a single device rather than layering systems. Deployment across seven UK Tier-1 contractors and TfL constitutes real early-stage evidence, though long-term compliance efficacy data has not been published and the evidence sits at one provided count. The cloud dependency is the structural risk to treat seriously: all dosimetry records and regulatory audit trails route through the SmartHub platform, and any service interruption creates evidentiary gaps at exactly the point where HSE or legal scrutiny would matter most. The SNR 29dB rating also needs to be matched to the actual noise environment — it is not suitable as the sole device for highest-attenuation tasks such as pneumatic breakers or pile driving, requiring a mixed PPE regime across site. Worker acceptance of continuous wearable monitoring introduces cultural and privacy friction that varies by site and workforce, and should be factored into rollout planning. Applicability outside the UK regulatory framework (OSHA, EU Directive 2003/10/EC variants) is not documented. A solid candidate for Tier-1 contractors running programmes where continuous dosimetry compliance and communication safety must coexist; confirm platform resilience and audit-trail backup before procurement.

Strengths

• Enables real-time continuous noise exposure mapping and compliance logging—eliminates sampling gaps in traditional audiometric data
• Active speech passthrough preserves site communication and hazard warnings while reducing occupational noise exposure
• Cloud-connected dosimetry integrates with safety management systems and removes manual record-keeping friction
• Dual-use: meets passive PPE + active intelligence compliance simultaneously, reducing dual-device overhead

Considerations

• Requires continuous device charging and cloud connectivity; loss of either degrades dosimetry completeness and real-time feedback (moderate)
• SNR 29dB is mid-range; does not meet highest-attenuation use cases (e.g., pneumatic breakers, pile driving); site must mix device types (moderate)
• Adoption and compliance depend on worker acceptance of wearable data collection and active monitoring; cultural/privacy friction on some sites (low)

Risks

• Category misalignment — product is hearing protection/occupational safety, not fire safety (high)
• Limited deployment data — early-stage adoption across 7 contractors; long-term compliance efficacy unproven (moderate)
• Cloud dependency — SmartHub/Peak platform creates single point of failure for dosimetry records and regulatory audit trails (moderate)
• Speech passthrough calibration — potential for over-attenuation of critical site warnings if algorithm fails (moderate)
• UK-centric validation — applicability to non-UK regulatory frameworks (OSHA, EU Directive 2003/10/EC variants) unclear (low)

Performance

• SNR (Sound Noise Reduction): 29dB
• Capped output level: 82–83dB
• Deployment scale: 7 UK Tier-1 contractors + TfL

Reality check

Deployment names and TfL award are independently verifiable and credible; EN352-1:2020 and IP65 certifications stated but not independently confirmed in excerpt. Eave.io source is company website (marketing context); no third-party test reports, peer-reviewed data on HearThrough efficacy, or long-term durability/failure analysis provided in record. Cloud platform security, data retention, GDPR compliance, and ROI claims not addressed. Noise cap specification (82–83dB) is borderline and may require supplementary controls on high-noise sites. SNR 29dB is adequate but not exceptional vs. premium passive defenders.
