Abstract

This study reports on the accuracy of smartphone sound measurement applications (apps) and whether they can be appropriately employed for occupational noise measurements. A representative sample of smartphones and tablets on various platforms were acquired, more than 130 iOS apps were evaluated but only 10 apps met our selection criteria. Only 4 out of 62 Android apps were tested. The results showed two apps with mean differences of 0.07 dB (unweighted) and -0.52 dB (A-weighted) from the reference values. Two other apps had mean differences within ±2 dB. The study suggests that certain apps may be appropriate for use in occupational noise measurements.

摘要

本研究报告了智能手机声音测量应用程序(应用)的准确性,以及它们是否可适用于职业噪声测量。我们获取了各平台上具有代表性的智能手机和平板电脑样本,评估了130多个iOS应用,但只有10个应用符合我们的选择标准。仅对62个安卓应用中的4个进行了测试。结果显示,有两个应用与参考值的平均差异为0.07分贝(未加权)和-0.52分贝(A加权)。另外两个应用的平均差异在±2分贝以内。该研究表明,某些应用可能适用于职业噪声测量。
