1. I have taken a sound reading and my sound level meter (SLM) is showing the result in Pascals, not dB (shouldn't have bought a cheap one). The maximum pressure shown is 101,008 Pa. Before the noise started, the air pressure was about 101,001 Pa, so the noise increased it by just 7 Pa. This doesn't seem right because the noise was really loud. Is my meter broken? What is the noise level in decibels (WRT 20μPa)?
