## Abstract

Kits, apparatuses, and methods are provided for measuring acoustic properties of a surface. In an implementation, a kit may be provided. The kit may comprise an elongated pin; a tube having first and second ends, the tube having at least one pair of diametrically opposing holes, the at least one pair of diametrically opposing holes operable to support the elongated pin therethrough; a mass adapted to be received through the first and second ends of the tube; wherein placement of the elongated pin through a first pair of the at least one pair of diametrically opposing holes may prevent movement of the mass through the tube; and wherein removal of the elongated pin through the first pair of the at least one pair of diametrically opposing holes may allow passage of the mass through the tube.

## Claims

### Claim 1

A method for measuring acoustic properties of a surface, the method comprising the steps of:
a) providing acoustic measurement instrumentation beneath the surface;
b) placing a mat upon the surface;
c) positioning a tube upon the mat, a length of the tube being perpendicular to the surface, the tube having at least one pair of diametrically opposing holes;
d) positioning an elongated pin through a first pair of the at least one pair of diametrically opposing holes;
e) positioning a mass within the tube such that the mass rests upon the elongated pin;
f) removing the elongated pin from the tube such that the mass falls through a bottom portion of the tube onto the mat thereby providing input to the acoustic measurement instrumentation;
g) obtaining a first resulting output by the acoustic measurement instrumentation;
repeating steps c) through f) a predetermined number of times;
obtaining a subsequent resulting output by the acoustic measurement instrumentation for each repetition;
receiving, by a computing device, the first resulting output and each of the subsequent outputs; and
determining an average resulting output by averaging the first resulting output and each of the subsequent outputs;
comparing the average resulting output to one or more sets of specifications, each of the one or more sets of specifications corresponding to one or more particular acoustic insulation apparatuses;
generating a user interface including a listing of one or more particular acoustic insulation apparatuses; and
presenting the user interface via the computing device.

### Claim 2 (depends on 1)

The method of claim 1, wherein the predetermined number of times is one time such that steps c) through f) are repeated one time and the average result is determined by averaging the first resulting output and a second resulting output.

### Claim 3 (depends on 1)

The method of claim 1, wherein the predetermined number of times is two times such that steps c) through f) are repeated two times and the average result is determined by averaging the first resulting output, a second resulting output and a third resulting output.

### Claim 4 (depends on 1)

The method of claim 1, wherein the surface is a slab floor.

### Claim 5 (depends on 1)

The method of claim 1, wherein the mat is formed of an elastomer and has a generally planar upper facing.

### Claim 6 (depends on 1)

The method of claim 1, wherein the tube has more than one pair of diametrically opposing holes to allow the elongated pin to be placed at different heights.

### Claim 7 (depends on 1)

The method of claim 1, wherein the mass is a sphere.

### Claim 8 (depends on 1)

The method of claim 1 wherein the tube, the elongated pin, the mass, and the mat have a combined weight that does not exceed 30 kilograms.
