Smart Alert Earplug

Minuendo certified hearing protection with real-time noise monitoring

£398.00 excl. tax | £477.60 incl. tax

Smart Alert enhances hearing loss prevention initiatives by integrating in-ear noise monitoring, certified hearing protection, and secure cloud-based data to address the challenges of dynamic noise environments. Designed for industries with fluctuating noise levels and mobile workers, it reduces the uncertainty and variability associated with the current risk assessment approach and the reliance on personal protective equipment.

Smart Alert helps users build safer habits by providing real-time alerts when noise levels become unsafe. Gentle audio, visual, and vibration prompts encourage immediate action, reducing the risk of over-exposure. These reminders encourage a proactive response, helping workers reduce their exposure and build long-term habits that prioritise their hearing health.

Safety Managers gain access to valuable insights into occupational noise exposure. Unique reports allow them to identify high and overexposed operators so they can focus their support on those individuals most at risk. With an emphasis on ease of deployment and reliability, Smart Alert transforms complex challenges into effective, actionable solutions that improve both safety and productivity.

  • Offers in-ear and ambient noise exposure monitoring, providing a comprehensive understanding of an individual’s actual exposure throughout their entire working shift.
  • Provides real-time user alerts, ensuring timely action when required and notifying users when exposure limits are exceeded.
  • Integrates an acoustic filter, enabling ambient sounds to be heard clearly, which prevents isolation and avoids the risks of over-protection.
