  • That air conditioner noise is annoying!

    The sound of the HVAC System in your office or factory may be annoying depending on who you ask; the person who has to live with it, or the person who has to pay for it. To measure background noise levels objectively, we use Noise Curves. International standards organizations (ISO, ANSI and ASA) recognize the need to objectify judgements on the amount of ambient noise in enclosed ...
