The Sound Level Meter is a piece of equipment used by Egon Spengler and Ray Stantz during the detection phase of an investigation.
History
In late 1989, Ray Stantz used the Sound Level Meter while going into the Orrefors crystal store. During the battle against Vigo on New Year's Eve, Egon Spengler used the Sound Level Meter to confirm that Vigo was still in the Manhattan Museum of Art.
Function
Like the Giga Meter, it appears to be an alternative to the P.K.E. Meter and measures an entity's unique frequency.
