Daily Noise Dose — review measured exposure in dB Pulse

Daily Noise Dose is a free dB Pulse view that accumulates a model-based dose from measured sound levels and shows a seven-day history sparkline. It uses the NIOSH reference model, but incomplete measurement periods and phone accuracy limits mean it cannot certify a safe day.

Find dose under Tools

Open Tools and choose Daily Noise Dose. The view summarizes accumulated dose alongside information about the current measurement. Its purpose is to put level and time together: a short high-level event and a longer lower-level event do not contribute equally to a dose model.

Before interpreting the result, check that the phone is measuring the environment you mean to describe. A microphone covered by a pocket, located far from your ears or routed to an accessory can represent something different. Calibration and consistent placement improve the usefulness of comparisons, but do not turn the phone into a personal certified dosimeter.

Understand the reference model

The app’s calculation uses the NIOSH reference of 85 dBA for eight hours with a 3 dB exchange rate. In that model, every additional 3 dB halves the permitted reference duration. The implemented accumulation counts measured levels at or above 80 dBA. This is a model assumption, not a statement that all lower levels are safe for every person or situation.

The percentage describes a proportion of the selected model’s daily reference exposure. A low percentage does not diagnose healthy hearing, and a high one does not diagnose injury. Use the display as a reason to review sound conditions and measurement coverage, rather than as a promise about an individual person’s response.

Count only what was measured

A daily display can look comprehensive even when it covers only part of the day. The app’s tracker uses incoming measurements and deliberately avoids charging a long inactive or background gap as though the last reading continued throughout it. It does not reconstruct unmeasured commuting, work or leisure time.

That behavior is essential to honest interpretation. If you measured a rehearsal but not the journey home, the result describes the measured contribution rather than your complete day. Do not fill the gap by assuming it was quiet. If total exposure matters professionally, use a suitable personal dosimeter and the required procedure.

Read the seven-day sparkline as context

The rolling seven-day sparkline makes it easier to notice differences between recorded days. It is useful for asking whether your measurement routine covered comparable activities. Compare a day measured throughout an event with another day measured in the same way, rather than comparing unequal coverage as if it were a controlled experiment.

Changes in microphone, calibration or where the phone was carried can also change the apparent pattern. Keep a note of those changes. A history graph does not remove the need to remember whether a day had long gaps or an unusual setup.

Reset Dose clears the current accumulation and timer while preserving the rolling history. Resetting is not a way to reconstruct intervals that were never measured.

Choose an action the number can support

The dose view can prompt a practical question: can the source be quieter, can you move farther away or can you take a quieter break? Suitable hearing protection and professional advice may be important in loud environments. Do not wait for the displayed percentage to cross a particular number before responding to obviously uncomfortable sound.

For a separate what-if calculation using known levels and durations, use the website noise-dose calculator. It is useful for comparing model assumptions without implying that the app measured the missing hours. For a workplace safety decision, calibrated equipment and an occupational assessment remain the appropriate route.
