Thank you for an occupational health viewpoint and the citation. Do you have a good recommendation for a recording dB meter and recording app suitable for graphing noise levels over a daylong period? Such a thing would be useful in proving the noise load of a busy open office and allow it to be compared to OSHA standards.
