| Product No. / Name | ETENWOLF S7 Tire Inflator (Air Pump) |
| Model / Specification | S7 |
| Manufacturer | ETENWOLF |
| Sample Quantity / No. | 3 PCS |
| Test Purpose | Evaluate the noise level of the S7 tire inflator during operation. |
| Test Conditions | Room temperature 23 °C, relative humidity 60 % |
Test Equipment & Setup
| Item | Detail |
|---|---|
| Test Equipment | Sound Level Meter (Noise Meter) |
| Microphone Distance | 1 m horizontal from the front face of the product |
| Measurement Direction | Front face (正面) |
| Device State During Test | Product powered on (operating state) |
| Ambient Temperature | 23 °C |
| Ambient Humidity | 60 % RH |
Test Procedure
- Pre-test: Verify ambient conditions — temperature 23 °C, relative humidity 60 %. Confirm the sound level meter is calibrated and operational.
- Sample placement: Position the S7 unit on a stable surface. Place the microphone at a horizontal distance of 1 m from the front face of the product.
- Power on: Switch the product to its normal operating (inflation) state.
- Measurement: Record the noise reading in dB from the sound level meter while the unit is running.
- Repeat: Perform the measurement for each of the three samples (4#, 6#, 12#) under identical conditions.
- Post-test: Power off all samples. Document all readings in the test record.
- Acceptance Criteria: No numeric pass/fail threshold defined — results are recorded for reference only per internal standard.
Test Data & Results
| Unit No. (编号) | Direction (方向) | Microphone Distance (距离麦克风距离) | Noise (dB) (噪音) |
|---|---|---|---|
| 4# | Front (正面) | 1 m | 80.2 |
| 6# | Front (正面) | 1 m | 82.7 |
| 12# | Front (正面) | 1 m | 81.7 |
Observations: All three units operated normally during testing. Noise readings ranged from 80.2 dB to 82.7 dB, with unit 6# producing the highest reading and unit 4# the lowest. The spread of 2.5 dB across units is within a typical unit-to-unit variation band for this product class. No abnormal sounds or mechanical anomalies were noted. Results are recorded for reference only; no numeric pass/fail limit is defined under the applicable internal standard.

Frequently Asked Questions
How loud is the ETENWOLF S7 tire inflator during operation?
During powered inflation, the S7 produces a front-face noise level of approximately 80.2 – 82.7 dB measured at 1 m distance. This is typical for a compact high-pressure tire inflator in its class.
What test standard was used for the S7 noise test?
The S7 noise test was conducted against ETENWOLF’s internal standard. No published external standard (such as IEC or ISO) was applied, so the results are recorded for reference only rather than as a formal pass/fail certification.
How was the noise level measured for the S7?
A sound level meter (noise meter) was positioned at a horizontal distance of 1 m from the front face of the S7 unit. The product was powered on in its normal operating state during measurement. Ambient conditions were 23 °C and 60 % relative humidity.
Did the ETENWOLF S7 pass the noise test?
Because the test uses an internal standard with no defined numeric pass/fail threshold, the results are classified as for reference only. All three samples functioned normally and produced consistent readings, confirming stable acoustic performance across units.
