Abstract
Abstract A device for facilitating correlation between the values, sound source distance, sound source volume and gain control setting, of an electroacoustical system including a microphone and an amplifier having a gain control, when two of these values are known, comprises a scale support carrying, in mutually fixed coordination, a first scale representative of the setting of the gain control, and at least one other scale representative of the distance of the sound source from the microphone. A slide on the support is movable along the scales and has a first indicator cooperable with the first scale and second indicator elements cooperable simultaneously with at least three adjacent indicia of each other scale. The device may comprise a unit physically independent of the microphone and the gain control, incorporated with the microphone, or incorporated with the gain control.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
106 words
In an electroacoustical system including a microphone and an amplifier having a gain control, a device for the numerical determination of one of the values sound source distance, sound source volume and gain control setting, when two of these values are known, said device comprising, in combination, a microphone housing element having a circular cross section; and a cylindrical element rotatably mounted on said circular cross section housing element; one of said elements carrying two scales each respective to one of said values, and the other of said elements carrying indicating means cooperable with said scales to coordinate said scales with respect to said third value.
Claim 2
Dependent Claim
106 words
In an electroacoustical system including a microphone and an amplifier having a gain control, a device for the numerical determination of one of the values sound source distance, sound source volume and gain control setting, when two of these values are known, said device comprising, in combination, a microphone housing element having a circular cross section; and a cylindrical element rotatably mounted on said circular cross section housing element; one of said elements carrying two scales each respective to one of said values, and the other of said elements carrying indicating means cooperable with said scales to coordinate said scales with respect to said third value.
Claim 3
Dependent Claim
38 words
A device, as set forth in claim 1, characterized in that said housing element constitutes a scale support; said cylindrical element comprising a ring rotatably mounted on said microphone housing element and having an aperture exposing said scales.
Claim 4
Dependent Claim
80 words
A device, as set forth in claim 2, characterized in that there are a plurality of a first type of scales each in mutually fixed relationship with one of a plurality of a second type scales; said ring having a plurality of apertures each exposing a respective one of said first type of scales and the associated one of said respective second type of scales; and each of said second type of scales being calibrated in different respective measuring units.
Claim 5
Dependent Claim
80 words
A device, as set forth in claim 2, characterized in that said ring includes a sleeve mounted on said microphone housing element for displacement longitudinally of said microphone housing element; there being a plurality of a second type of scales, each calibrated in different respective measuring units, said second type of scales being displaced longitudinally of said microphone housing element; and said sleeve being formed with a window exposing only one of said second type of scales at a time.
Claim 6
Dependent Claim
17 words
A device, as claimed in claim 2, in which said gain control is incorporated in said microphone.
