Rule 504:

 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 503 of this Part must

be measured before competing in terms of A-weighted sound

levels using sound level meters

 in conformance with ANSI

Standards S1,4 Type

I

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 503

under

static test conditions.

Cc)

 On and

after March 15,

 1979, before any motorcycle

 racing

vehicle

required to

have

 a muffler in accordance with

 Rule

503 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 S1.4 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

manufacturerts—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 eng ne 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

28

—

calculated

from

either

the

following

formulae:

Engine Speed

 306,000

stroke

in

millimeters

OR

Engine Speed

in

inches

Rule 505:

 Drag Racing Facilities--Sound Emission Limits

On and after March 15,

racing vehicle, all mufflers required in accordance with this

Rule 506(a)

 shall meet the requirements specified in Rule 506

 Supercharged oval racing vehicles.

(c)

 Except for any motorcycle used as an oval racing vehicle, all

mufflers required

 in accordance with Rules

 507(a)

 of this Part

shall have noise reducing characteristics which will produce a

reduction

 in total vehicle noise of at least the amount listed

in Table

 2 when such oval racing vehicle is operated in

a

manner simulating wide—open throttle competition.

 Such noise

reduction shall be determined by using measurement procedures

specified in Rule 103 of this Chapter.
