Sound Meter Pro的描述

Sound Meter Pro is the 4th set of Smart Tools collection (noise, vibration, seismometer).

SPL(sound pressure level) meter app uses your built-in microphone to measure noise volume in decibels(db), and shows a reference. We had calibrated many android devices with the actual sound level meter with dB(A).

REMEMBER!! The smart phone microphones were aligned to human voice (300-3400Hz, 40-60dB).

Therefore the maximum values are LIMITED by the hardware limitation, and very loud sound(100+ db) cannot be recognized. Moto Droid (max.100), Galaxy S3 (81dB), Galaxy Note (91dB), Galaxy S2 (98dB), HTC Desire(82dB)...

Vibrometer app uses the phone sensors to measure vibration or the earthquake, and it shows a reference as a seism detector.

The measured values are the Modified Mercalli Intensity scale(MMI), and just for reference.

If it is inaccurate, you can calibrate it so that the maximum value is about 10-11.

* Pro version added Features:

- Sound Meter and Vibrometer are integrated

- Statistic menu with saving log data

- CSV file exporting

- Level notification

- Line-chart duration

** Not Compatible with: Xperia(X8, X10 mini), LG(Optimus One, P350), GT-I9001, ZTE, etc声级计Pro是第四一套智能工具收集,(噪声,振动,地震仪)。

SPL(声压级)仪表的应用程序使用内置的麦克风来测量噪音的音量分贝(db),并给出了参考。我们已校准的许多Android设备的实际声级计分贝(A)。

记住!智能手机话筒对准人类语音(300-3400Hz的40-60DB)。

因此,最高值是有限的硬体限制,非常响亮的声音(100 + DB)不能被识别。 MOTO DROID(最高100),银河S3(81分贝),银河注(91分贝),银河S2(98分贝)的,宏达Desire(82分贝),...

测振仪的应用程序使用手机的传感器来测量振动或地震,并作为一个地震检测器,它显示了一个参考。

测量值修改麦加利强度量表(MMI),仅供参考。

如果它是不准确的,你可以这么校准的最高值大约是10-11。

* Pro版本增加的功能:

- 集成声级计,测振仪

- 保存日志数据统计菜单

- CSV文件导出

- 级别通知

- 线图持续时间

- 更多模型校准

- 没有广告
