| Product No. / Name | ETENWOLF S5 Tire Inflator (充气泵) |
| Model / Type Specification | S5 |
| Sample Quantity / No. | 3 PCS — S5-1#, S5-2#, S5-3# |
| Test Purpose | Evaluate noise conditions of the S5 / S6 / S3 tire inflator series |
| Test Environment | Room temperature 23 °C, relative humidity 60 % |
Test Equipment & Setup
| Item | Detail |
|---|---|
| Test Equipment | Sound Level Meter (噪音计) |
| Measurement Quantity | Sound Pressure Level, dB(A) |
| Microphone Position | Horizontal distance 1 m from the front face of the product |
| Product Operating State | No-load power-on (无负载开机状态) |
| Ambient Temperature | 23 °C |
| Relative Humidity | 60 % |
Test Procedure
- Pre-test: Confirm ambient conditions are 23 °C and 60 % RH. Verify sound level meter calibration.
- Sample preparation: Place the S5 unit on a flat surface. Ensure no inflation hose or load is attached (no-load state).
- Microphone placement: Position the microphone horizontally at 1 m from the front face of the product, at the same height as the product.
- Measurement: Power on the product in no-load state and record the steady-state A-weighted sound pressure level in dB(A).
- Repeat: Perform the measurement for each of the three samples (S5-1#, S5-2#, S5-3#).
- Post-test: Power off each unit. Record all readings in the test log.
Acceptance Criteria: No external pass/fail threshold is defined for this test. Results are recorded for reference only (供参考 / For reference only).
Test Data & Results
| Sample No. (编号) | Measurement Direction (方向) | Microphone Distance (距离麦克风距离) | Sound Pressure Level dB(A) (噪音声压级 dB(A)) |
|---|---|---|---|
| S5-1# | Front face (正面) | 1 m | 82.9 |
| S5-2# | Front face (正面) | 1 m | 83.5 |
| S5-3# | Front face (正面) | 1 m | 83.7 |
Observations: The three samples showed close agreement with a spread of 0.8 dB(A). No anomalous readings or equipment faults were noted during testing. Results are logged for reference and product benchmarking purposes.

Frequently Asked Questions
How loud is the ETENWOLF S5 tire inflator during operation?
Under no-load conditions at 1 m from the front face, the S5 produces a sound pressure level of approximately 82.9 – 83.7 dB(A). This is consistent across the three units tested and is typical for compact single-cylinder tire inflators in this power class.
What test standard was used for the S5 noise measurement?
The test followed ETENWOLF’s internal standard. No external standard (such as ISO 3744 or IEC) was specified, and no external pass/fail threshold was applied. The results are recorded for reference and product benchmarking only.
How was the noise measurement taken?
A sound level meter was placed horizontally at 1 m from the front face of the S5 unit. The inflator was powered on in a no-load state (no hose or load attached) and the steady-state A-weighted sound pressure level in dB(A) was recorded. Ambient conditions were 23 °C and 60 % relative humidity.
Did the ETENWOLF S5 pass the noise test?
The test did not apply a pass/fail threshold — results are designated “For Reference Only” (供参考). All three S5 samples returned closely grouped readings between 82.9 and 83.7 dB(A), providing a reliable acoustic baseline for the S5 product line.
