Review: 安い騒音計の精度はどのくらいか、疑問に思っていたが、B&Kの1/2マイク校正器で計ると、94dBのマイク感度の誤差は0.5 dB以内に収まっていた。感度補正はできないようだが、この程度の誤差なら問題ない。ただし周波数特性や指向特性、リニアリティは調べていないので、気になる人は、ピンクノイズをスピーカから再生させて、iPhoneの騒音計アプリと比べてみるとよいでしょう。
Review: スマホの騒音測定アプリは、表示が使い易くて良いのですが、 問題はその数値が合っているかどうか。 この商品は校正が多分出来ているんでしょうね。 取説にも、校正してあるっぽく書かれてますし。

## Questions & Answers

**Q: Why doesn’t the TS-501B show 0 dB in a quiet environment?**
A: The TS-501B measures from 30–130 dB and does not start at 0 dB. When sound levels are below 30 dB, it displays “UL” (Under Limit). In a quiet environment, it reads between 30 and 45 dB.

**Q: What scenarios are sound level meters usually used for?**
A: Sound level meters are often used for measuring community or environmental noise; Use for measuring noise produced by machinery in industries; Use for calibrating audio equipment at concerts or for personal reasons.

**Q: What is the difference between A Frequency Weighting and C Frequency Weighting?**
A: The A-weighting adjusts the sound pressure level readings to reflect the sensitivity of the human ear and is used for hearing damage risk measurements. The C-Weighting is used for Peak measurements and also in some entertainment noise measurements.

**Q: What is the difference MAX/MIN Value between A-Weighting and C-Weighting?**
A: MAX/MIN Value of A-Weighting is Lmax/Lmin (the highest and lowest values measured by the sound level meter over a given period of time.); MAX/MIN Value of C-Weighting is Lpeak (the max/min value of the absolute instantaneous sound pressure).

**Q: Decibel Levels: Typical Scenarios**
A: 30-40 dB: Library, bedroom. 50-60 dB: Restaurant, café. 70-80 dB: City roads, factory machinery. 90-100 dB: Rock concert. 110-130 dB: Jet airplanes, front row at a concert.

スマホの騒音測定アプリは、表示が使い易くて良いのですが、 問題はその数値が合っているかどうか。 この商品は校正が多分出来ているんでしょうね。 取説にも、校正してあるっぽく書かれてますし。
