Test Equipment & Setup
| Item | Detail |
|---|---|
| Test Equipment | Sound Level Meter (噪音计) |
| Microphone Position | 1 m horizontal distance from the front face of the product |
| Product State | Powered on and operating |
| Measurement Direction | Front face (正面) |
| Assessed SPL Range | Lmax 35–100 dB |
| Ambient Temperature | 23 °C |
| Relative Humidity | 60% |
Test Procedure
- Pre-test: Confirm ambient conditions — temperature 23 °C, relative humidity 60%. Verify sound level meter calibration.
- Sample preparation: Label three S1 units as 1#, 2#, and 3#. Place each unit on a stable flat surface in the test area.
- Microphone placement: Position the microphone at a horizontal distance of 1 m from the front face of the product at the same height as the unit.
- Measurement: Power on the product and record the maximum sound pressure level (dB) displayed on the sound level meter for each sample.
- Post-test: Power off each unit after measurement. Record all readings and verify they fall within the assessed range of Lmax 35–100 dB.
Acceptance Criteria: Sound pressure level must fall within the assessed range of 35–100 dB (Lmax). Results are recorded for reference; no pass/fail threshold is applied under the internal standard for this test.
Test Data & Results
| Sample No. | Direction | Distance to Microphone | Noise (dB) |
|---|---|---|---|
| 1# | Front (正面) | 1 m | 84.8 |
| 2# | Front (正面) | 1 m | 80.9 |
| 3# | Front (正面) | 1 m | 80.8 |
Observations: Sample 1# registered the highest reading at 84.8 dB, while samples 2# and 3# were closely grouped at 80.9 dB and 80.8 dB respectively. All three readings fall within the internal assessed range of 35–100 dB. The spread between the highest and lowest readings is 4.0 dB. No anomalous noise events were noted during testing. Results are classified as for reference only and do not constitute a pass or fail determination under the current internal standard.

Frequently Asked Questions
How loud is the ETENWOLF S1 tire inflator during operation?
In noise testing conducted at 1 m front-face distance, the S1 recorded readings between 80.8 dB and 84.8 dB across three samples. This is consistent with the operating noise level of a typical portable tire inflator and falls well within the internal assessed range of 35–100 dB.
What test standard was used for the S1 noise test?
The S1 noise test used ETENWOLF’s internal standard for sound pressure level assessment, with an evaluated range of Lmax 35–100 dB. The test is classified as a Reliability Test and the results are recorded for reference only.
How was the noise measurement taken for the S1 inflator?
A sound level meter was positioned at a horizontal distance of 1 m from the front face of the powered-on S1 unit. Testing was conducted at room temperature (23 °C) and 60% relative humidity. Three separate samples were each measured individually.
Does the ETENWOLF S1 pass the noise test?
The S1 noise test is classified as for reference only under the current internal standard, meaning no explicit pass or fail threshold applies. All three samples measured between 80.8 dB and 84.8 dB, within the assessed SPL range of 35–100 dB.
