Acoustic data collected at sites (lakes) for comparison of hydro (below water) and air (above water) sound characteristics. Data is summarized by site (field=Lake_Name) and includes total average power of all sound samples over all time periods (field=Power) as well as for each 1 kHz frequency interval (e.g. 3to4kHz_Power). All power is in decibels (db) calculated in Raven Pro 1.4
