Test Equipment & Setup
| Item | Details |
|---|---|
| Test Equipment | Sound Level Meter (噪音计) |
| Microphone Placement | 1 m horizontal distance from the front face of the product |
| Measurement Direction | Front face (正面) |
| Ambient Temperature | 23 °C |
| Relative Humidity | 60 % |
| Test Conditions Label | Room Temperature & Humidity: 23 °C, 60 % |
Test Procedure
- Pre-test: Confirm ambient temperature (23 °C) and relative humidity (60 %) are within specified conditions. Verify the sound level meter is calibrated and ready.
- Sample placement: Position the HB1 blower pump on a stable surface. Place the sound level meter microphone at 1 m horizontal distance from the front face of the product.
- Power on: Switch the product to its powered-on operating state.
- Measurement: Record the maximum sound pressure level (dB) displayed on the sound level meter for each sample unit.
- Repeat: Perform the measurement for all three samples (7#, 8#, 9#) under identical conditions.
- Post-test: Power off each unit after measurement. Record all readings and compare against the evaluated criterion (Lmax 35–100 dB).
- Acceptance criteria: Results are evaluated against a sound pressure level range of Lmax 35–100 dB. This test is for reference only; no pass/fail verdict is assigned.
Test Data & Results
| Sample No. (编号) | Direction (方向) | Distance from Microphone (距离麦克风距离) | Noise Level — dB (噪音) |
|---|---|---|---|
| 7# | Front (正面) | 1 m | 70.9 |
| 8# | Front (正面) | 1 m | 69.8 |
| 9# | Front (正面) | 1 m | 72.5 |
Observations: All three samples operated within the evaluated sound pressure range of 35–100 dB. Sample 9# recorded the highest level at 72.5 dB; Sample 8# recorded the lowest at 69.8 dB. The spread across samples is 2.7 dB, indicating consistent acoustic output across the production lot. No anomalies were noted during measurement.

Frequently Asked Questions
What is the measured noise level of the ETENWOLF HB1 blower pump?
During testing, the three HB1 samples recorded sound pressure levels of 70.9 dB, 69.8 dB, and 72.5 dB at 1 m horizontal distance from the front face while powered on. The average is approximately 71.1 dB.
What test standard was used for the HB1 noise test?
The test followed ETENWOLF’s internal standard, evaluating the sound pressure level (Lmax) of the noise source against a criterion range of 35–100 dB. No third-party international standard was applied for this report.
Does the HB1 blower pump pass the noise test?
This report is classified as For Reference Only. No formal pass or fail verdict was issued. All three samples fell within the evaluated range of 35–100 dB, confirming typical operational noise characteristics.
How was the HB1 noise measurement conducted?
The product was powered on and a calibrated sound level meter was positioned with its microphone at exactly 1 m horizontal distance from the front face of the unit. Measurements were taken under stable indoor conditions at 23 °C and 60 % relative humidity.
