What happened and what to do
On March 3, 2026, the article compared claims about a portable audio blocker with existing ultrasonic blockers and DIY kits. It points to possible limitations in device detection and range, as well as effects from room reflections, fabrics, and obstacles.
For a company evaluating this type of hardware, a practical response is to test coverage across different environments and conditions, record the results, and define usage criteria and privacy alternatives. This helps prevent the blocker from being treated as a guarantee without proper evaluation.
