صدا چیست؟
وقتی تغییرات فشار هوا موجب تولید امواجی از فشار شده که در اتمسفر منتقل می شود صوت ایجاد می شود . هنگام عبور، این امواج به روش های گوناگونی با محیط خود ارتباط دارند. صدا واژه ای است که ناخود آگاه برای صوت به کار برده می شود . طریقه انتقال صوت به صورت موج است که موج سینوسی معمول ترین نوع موج صوتی است که در یک سمت و بدون واگرایی از منبع تولید دور می شود.
برای اندازه گیری تراز فشار صوت ، صوت سنج ساخته شده است .
تعریف صوت سنج یا صداسنج Sound Level Meter
صوت سنج دستگاهی است که قابلیت اندازه گیری پارامتر صدا بر حسب دسی بل را دارد. معمولا صوت سنج های موجود از نوع صوت سنج دیجیتال پورتابل بوده و نمونه های حرفه ای آن قابلیت آنالیز صوت ( آنالیزور صوت ) و ذخیره مقادیر اندازه گیری شده ( دیتالاگر صدا ) را دارد.
