Test Equipment & Setup
| Item | Detail |
|---|---|
| Test Equipment | Sound Level Meter (Noise Meter) |
| Measurement Distance | 1 m horizontal from the front face of the product |
| Device State During Test | Unit powered on (operating state) |
| Ambient Temperature | 23 °C |
| Relative Humidity | 60 % |
| Test Environment | Room temperature and humidity conditions |
Test Procedure
- Pre-test: Confirm ambient conditions — temperature 23 °C, relative humidity 60 %. Verify sound level meter calibration.
- Sample preparation: Label three HB2 units as 1#, 2#, and 3#. Ensure each unit is fully assembled and functional.
- Microphone positioning: Place the sound level meter microphone at 1 m horizontal distance from the front face of the unit under test, at the same height as the unit.
- Measurement: Power on the unit. Allow it to reach steady operating state. Record the noise reading in dB from the sound level meter.
- Repeat: Perform the same measurement for each of the three samples in sequence.
- Post-test: Power off all units. Record all readings and environmental conditions in the test log.
Acceptance Criteria: No normative pass/fail limit is defined for this test. Results are logged for reference only (■ For Reference Only).
Test Data & Results
| Sample No. | Direction / Orientation | Distance from Microphone | Noise (dB) |
|---|---|---|---|
| 1# | Front Face (正面) | 1 m | 76.8 |
| 2# | Front Face (正面) | 1 m | 72.6 |
| 3# | Front Face (正面) | 1 m | 71.1 |
Observations: All three units were measured from the frontal direction at a 1 m standoff distance. Unit 1# returned the highest reading at 76.8 dB. Unit 3# returned the lowest at 71.1 dB. The spread across samples is 5.7 dB. No photographic test images have been included in this data extract. Because no normative upper limit was specified in the test standard field, the overall assessment is recorded as For Reference Only.

Frequently Asked Questions
How loud is the ETENWOLF HB2 inflator pump during operation?
In controlled testing at 1 m frontal distance with the unit powered on, the three HB2 samples measured between 71.1 dB and 76.8 dB. The peak reading was 76.8 dB on sample 1#.
What test standard was used for the HB2 noise test?
The test was conducted against ETENWOLF’s internal standard. No external normative standard (such as IEC or ISO) was specified, so no pass/fail threshold was set. The results are recorded for reference only.
How was the noise measurement taken for the HB2?
A sound level meter was positioned at exactly 1 m horizontal distance from the front face of the HB2 unit. Each unit was powered on and in operating state during measurement. The test environment was held at 23 °C and 60 % relative humidity.
Did the ETENWOLF HB2 pass the noise test?
Because no normative upper noise limit was defined for this test, a formal pass or fail verdict was not issued. The assessment is marked as For Reference Only, meaning the data serves as a baseline record for the HB2 model rather than a compliance determination.
