3.0 TERMINOLOGY

3.1 Definitions

3.1 .I " A Weighed Decibel dB(A)

A measure of sound levels as experienced by humans, calculated using a spectral sensitivity factor (A-Filter) that weights sound pressure levels by frequency to correspond to th~e sensitivity of the human ear.

3.1.2 Continuous Noise

When the sound intensity reaches peak values at an interval of one (1) second or less.

-.

DOC. NO. KOC-L-030

3.1.3 Decibel (dB)

It is the unit for measuring extent of noise to which human ear is exposed. It is calculated by the logarithmic:: difference between the pressure of the sound desired to measure its intensity (A) and the pressure of the lease sound (Po), which the human ear may hear, which is 20 micro Pascals, as specified by the measuring device compatible with the international standard specifications ISO-176.

3.1.4 Directivity Factor

When sound radiates from a source, sound levels can be higher in certain directions. This is termed (as "directivity". Directivity factor is ratio of the increased sound pressure level to the average sound pressure value.

3.1.5 Directivity Index

Directivity index, expressed in dB, is the difference of the increased sound pressure level to the average sound pressure value.

3.1.6 Free Field

An open area on a flat surface in which to make measurements, with no solid surfaces in vicinity to reflect the sound back to the measurement point.

3.1.7 Fast Response

Dampening on meters so that it takes 125 milliseconds to move over 10 dB. This is the setting normally used.

3.1.8 Frequency Analysis

Analysis of the intensity of sound by frequency. Usually done by octave bands or one third octave bands. This analysis is important for formulating control measures. The ce~ntre frequencies of filter passbands have been standardised internationally and are specified in IEC 225. These are 31.5, 63, 125,250, 500, 1000,2000, 4000,8000, and 16000 Hz.

3.1.9 Impulse Noise

Noise consisting of a single pressure peak, or a sequence of such peaks, or a s~ngle burst with multiple pressure peaks, or a sequence of such bursts.

7

DOC. NO. KOC-L-030

3.1.10 Maximum Sound Pressure Level

The maximum sound pressure level (L,,,,) is the highest value recorded.

3.1.11 Narrow Band Noise - Pure Tone

Where a dominant noise component is audible over a single frequency or narrow band width.

3.1 . I 2 Noise

Are the undesired sounds resulting from sound waves emitted from indoor or outdoor sources which have immediate rapid effect on the activity of workers, which may affect their hearing ability.

3.1.13 Pascal Squared Hour

A measure of sound exposure. 1.0 pa2 h is equivalent to an average level of 85 dB for 8 hours.

3.1 .I4 Peak Sound Pressure Level

This is a measure of the greatest pressure, either positive or negative that was received in the time per~od measurement.

The formula is given below:

Square of the greatest overpressure L peak = 10 /OgqO ------------..--------------------------------------

po2 where:

Overpressure is in pascals po is reference value 20pPa

3.1.15 Slow Response

Dampening on meters so that it takes one second for the needle to move over 10 dB.

3.1.16 Reverberant Field

An area having near field solid surfaces that will reflect noise resulting in an increase in measured noise level.

KUWAIT ENVIRONMENTAL PROTECTION AUTHORITY (KEPA) NOISE STANDARDS

A. GENERAL

Harmful exposure to sound intensity in working areas shall be eliminated or minimized by proper planning and careful designing. Noise control considerations include substitution with quieter sources, isolation, enclosure, baffling, resilient mounting, sound absorption, or such other measures as appropriate.

B. PROTECTION

When the sound intensity in a working area exceeds 85 decibels (dBA) overall, then appropriate personal ear protective devices shall be required.

When the sound intensity in a working area exceeds 115 dBA, suitable personal protective equipment in combination of earplugs and earmuffs shall be required to reduce the resultant affect on the workers exposed.

C. NOISE MEASUREMENT

Measurement of sound intensity shall be taken by qualified personnel in consultation with Health & Environment Team. Moreover the measurement of sound intensity should be carried out at one (1) metre away from the source and 1.5 metre above the ground level.

D. OCCUPATIONAL NOISE EXPOSURE

Protection against the noise exposure shall be provided when the sound intensity exceeds the level (measured at: slow response) as indicated in Table I of this Standard.

(i) When workers are exposed to sound intensity exceeding the limits as listed in the table, then feasible administrative or engineering controls shall be applied. If such controls fail to reduce sound levels within the desirable limit, then the workers prior to entering the area shall wear appropriate personal protective equipment.

(ii) No exposure is allowed to a continuous, intermittent or impact noise in excess of 140 dBA.

(iii) Sound level in decibels are measured on a sound level meter, conforming to the minimum requirement of the American National Standards Institute "Specification For Sound Level Meters1' (ANSI S1.4).

(iv) Limited to the noise source but not as an administrative control measure; it is recommended to use a dosimeter or integrating sound level meter for sounds intensity above 120 decibels.

-


(v) If the sound intens~ty reaches peak values at an interval of one (1) second or less, the noise level is considered to be continuous.

(vi) In all cases where the sound intensity exceeds the values shown herein, a continuous & effective hearing conservation program shall be administered.

E. CONTINUOUS OR INTERMITTENT NOISE

The sound pressure level should be determined by a sound level meter or dosimeter conforming, as a minimum requirement to American National Standards Institute (ANSI) Specification for Sound Level Meters, S1.4-1983, Type S2A, or ANSI S1.25-I 991 Specification far Personal Noise Dosimeters.

The measurement device should be set to use the A-weighted network with slow meter response. The duration of exposure should not exceed the limit as mentioned in Table 1 of this Standard. These values apply to total duration of exposure or a number of short-term exposures.

F. COMPUTING NOISE LEVELS

When the daily noise exposure IS composed of two or more periods of noise exposure of different levels, their combined effect should be considered rather than the individual effect of each.

If the sum of the following fractions exceeds unity :

c 1 c2 - C n + - --

TI T2 1-n

then the mixed exposure should be considered to exceed the TLV.

Where,

Cq = indicates the total duration of exposure at a specific noise level.

TI = indicates the total duration of exposure permitted at that level.

(i) All on job noise exposures effect of 80 dBA intensity or above should be considered based on the above calculations.

(ii) While measuring with sound level meters, the above formula should be used for sounds having steady levels of at least three (3) seconds.

(iii) Where this condition can riot be met, a dosimeter or an integrating sound level meter must be used.

1

(iv) The TLV is considered exceeded when the dose is more than 100% as indicated on a dosimeter set with a three (3) dB exchange rate and 8-hour criteria level of 85 dBA.

(v) The TLV is considered exceeded on an integrating sound level meter if the average sound level exceeds the values as indicated in Table-I of this Standard.
