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 |
| Measurement Direction | Front face (正面) |
| Ambient Temperature | 23 °C |
| Ambient Humidity | 60 % |
| Device Operating State | Powered on (开机状态) |
Test Procedure
- Pre-test: Confirm ambient conditions — temperature 23 °C, relative humidity 60 %. Verify the sound level meter is calibrated and operational.
- Sample preparation: Label three TB1 units as 1#, 2#, and 3#. Place each unit on a flat surface in its normal operating orientation.
- Microphone placement: Position the microphone at 1 m horizontal distance from the front face of the unit under test.
- Operation: Power on the unit. Allow it to reach stable operating speed before recording.
- Measurement: Record the noise level in dB from the sound level meter for each sample.
- Post-test: Power off the unit. Record results and compare against reference benchmarks if applicable.
- Acceptance criteria: No formal pass/fail threshold defined; results are recorded for reference only.
Test Data & Results
| Sample No. (编号) | Direction (方向) | Microphone Distance (距离麦克风距离) | Noise Level — dB (噪音) |
|---|---|---|---|
| 1# | Front (正面) | 1 m | 72.2 |
| 2# | Front (正面) | 1 m | 72.3 |
| 3# | Front (正面) | 1 m | 71.4 |
Observations: The three samples showed consistent noise readings, with a spread of only 0.9 dB. The highest recorded value was 72.3 dB (Sample 2#) and the lowest was 71.4 dB (Sample 3#). No anomalies or irregularities were noted during testing. No test images were captured in this report cycle.

Frequently Asked Questions
What noise level does the ETENWOLF Air3 TB1 produce during operation?
In testing conducted on 2025-03-07, the three Air3 TB1 samples measured 72.2 dB, 72.3 dB, and 71.4 dB respectively, all recorded at 1 m front-face distance with the unit powered on under standard room conditions (23 °C, 60 % RH).
What measurement standard was used for the Air3 noise test?
The test was conducted against ETENWOLF’s internal standard. No external standard (such as IEC or ISO) was specified for this particular evaluation. Results are recorded for reference purposes only.
How was the microphone positioned during the Air3 noise measurement?
The sound level meter microphone was placed at a horizontal distance of 1 m directly in front of the product (front-face orientation) while the unit was running at normal operating speed.
Did the Air3 TB1 pass or fail the noise test?
No formal pass/fail threshold was applied to this test. The report is marked For Reference Only (供参考), meaning the noise data is intended to establish a baseline rather than to certify compliance against a specific limit.
