Acoustic Safety
Consulting Services
Allion provides “Safe Acoustic Earbuds” testing and consulting services. We help brands validate whether ANC modes, Transparency modes, and various earphone products retain the perceptibility of critical external sounds—such as alarms, broadcasts, cries for help, and industrial safety warnings—in real-world usage scenarios.
InquiryWhy “Safe Acoustic Earbuds” Validation is Needed Now
In recent years, the earphone market has rapidly evolved toward high acoustic isolation, active noise cancellation, and immersive listening experiences. However, in scenarios such as commuting, campuses, sports, industrial sites, and home environments, users must maintain basic awareness of critical external sounds. When earphones overly block external noise, or cause users to miss warning signals during music playback, calls, or ANC modes, the product risk goes beyond acoustic performance to become a public safety issue. This involves various usage scenarios with differing levels of safety risks and, more importantly, impacts invaluable brand reputation.
Services Provided by Allion
| Service Module | Key Content | Value to Customer |
| Acoustic Safety Event Database Creation | Key Content: Defining target sounds such as alarms, horns, broadcasts, cries for help, and industrial warnings, while organizing parameters like sound pressure, frequency spectrum, distance, direction, and background conditions. | Translating abstract “feelings of safety” into measurable targets and scenarios. |
| Sound Penetration and Perceptibility Validation | Validating whether critical external sounds remain detectable and recognizable under ANC ON/OFF, Transparency mode, music playback, or call conditions. | Applicable for product validation, specification confirmation, and pre-launch quality control. |
| Human Factors and Scenario Simulation Evaluation | Designing participant tasks based on commuting, campus, home, sports, and industrial scenarios to evaluate detection rate, recognition rate, and reaction time. | Closer to real-world usage scenarios, avoiding reliance solely on isolated laboratory data. |
| Tuning and Debugging Consulting | Providing problem analysis and improvement recommendations for acoustic tuning, algorithm thresholds, mode switching, and notification strategies. | Not only identifying problems but also knowing where to prioritize improvements. |
| Benchmark and Marketing Claim Support | Comparing differences in critical sound retention across various designs or competing products, and supporting marketing claims and legal risk reviews. | Beneficial for product positioning, external communication, and customer complaint risk management. |
- Detection Rate: Whether the user notices an event occurring when a target sound is present.
- Recognition Rate: Whether the user can further identify the type or meaning of the sound.
- Reaction Time: The time difference between the event occurring and the user reacting.
- False Negative / False Positive: Whether the system misses critical sounds or overly intervenes, causing interference.
- SPPI: Integrating multiple performance metrics into a consolidated, easy-to-communicate evaluation result.
- Define product positioning and selling points with greater confidence.
- Support marketing claims and external communications with solid data.
- Early detection of design flaws in ANC, Transparency mode, or notification strategies
- Serves as a common language aligning R&D, PM, Marketing, and Legal teams.
- Establishes a benchmark and a comparative baseline for future product generations.
