Rule

404:

Drag Racing Facilities--Sound Level Measurement

Requirement

(a)

The sound emissions from each drag racing vehicle required to

have a muffler in accordance with Rule 403 of this Part must

be measured before competing in terms

of A—weighted sound

levels using sound level meters in conformance with ANSI

Standards Sl.4 Type

1 or Type

2 requirements and using pro-

cedures specified in Rule 103 of this Chapter.

All sound

level measurements must be made with the microphone one—half

meter from the exhaust outlet with the engine gear—box in

neutral at an engine speed of 4000 rpm.

It shall be the

responsibility of the drag racing facility’s owners or

operators,

or designated agent,

to measure and record the

required sound level data.

Upon reasonable request,

the

owner or operator shall make such recorded sound level data

available to the Agency.

The owner and operator must keep

such recorded sound level data for the duration of the

racing season.

(b)

The Agency shall publish techniques for determining compliance

with Rule

403 under static test conditions.

(c)

On and after March 15,

1979,

before any motorcycle racing

vehicle required to have a muffler in accordance with Rule

403 of this Part competes at a drag racing facility,

the

noise emissions from such motorcycle racing vehicle must

be measured in terms of A-weighted sound levels using sound

level meters in conformance with ANSI Standards Sl.4 Type

1

or Type

2 requirements and using procedures

specified in

Rule 103 of this Chapter.

The microphone shall be located

one—half meter from and in the horizontal plane of the rear—

most exhaust outlet at an angle of

45 degrees behind the

exhaust outlet and from the normal line of travel of the

motorcycle.

The engine shall be run with the gear—box in

neutral at an engine speed equal to one-half of the

manufacturer’ s-recommended—maximum—engine—speed.

If no

manufacturer’s-recommended—maximum—engine—speed

is published

for a particular motorcycle,

then an engine speed equal to

60 percent of the engine speed at which maximum horsepower

is developed shall be used.

If no manufacturer’s-

recommended—maximum—engine—speed

is published,

then the

engine

speed

during

the

sound

level

measurement

shall

be

calculated from either of the following formulae:

Engine Speed

=

306,000

stroke in millimeters

OR

Engine Speed

=

12,000

stroke

in inches
