Abstract-The rapid urbanisation, increase in the volume of vehicular traffic and commercial activities have led to the serious environmental problem of noise pollution. In the present study noise pollution level has been measured in the residential, commercial, transport, industrial, silent zones of Amravati and compared with guidelines of Central Pollution Control Board (CPCB). The noise pollution was measured by using sound level meter at 22 monitoring locations during rainy, winter and summer seasons. The performance of several noise indices such as Leq, Lmax, Lmin, L10, L50, L90, NC, LNP and TNI were assessed. The results showed that most of the locations of Silent, Residential, Commercial and Transportation zones were above the permissible limits of CPCB while Industrial zones were within the limits. The highest exceedances were recorded at silentzoneslocationS1 (61.6% above the limit in winter), residential zone R5 (41.4%), commercial zone C2 (32.2%) and transport zone T2 (18.5%). Maximum noise was observed in winter with seasonal variation, followed by rainy and summer seasons because of increased vehicular traffic, honking and roadside commercial activities, crowding and atmospheric conditions (temperature inversion, increased humidity, low wind) that reduce sound dispersion. The study highlights the need for focused traffic management, strict implementation of CPCB rules, public awareness campaigns and constant monitoring to mitigate urban noise pollution.

2.6 CPCB ambient noise standards
Thecomputednoiseindicesarecomparedwithpermissible limitsprescribedbytheCPCBfordifferentzonesasshownin Table 6. The CPCB has prescribed Ambient Air Quality Standards in respect of Noise underthe Noise Pollution (Regulation and Control) Rules, 2000 (under the Environment Protection Act, 1986). These standards are widelyusedin environmental impact assessment. These limitsare defined as equivalent continuous sound level (Leq), representing average noise over a period. And is crucial for assessing compliances and planning effective noisemitigationstrategies.SinceCPCBdoesnotprescribea separate category for transport zones, traffic/transportdominated areas were considered under the Commercial Area category as per CPCB Ambient Noise Standards and mixedland-useprovisions.

3.1 Zone wise comparison with CPCB ambient noise standards
3.1.1 Silent zone:
FindingsfromtheanalysisofSilentZones(S1-S7)indicated thatallthreeseasonswereabovetheCPCBpermissiblelevel ofSoundEmission.Allthreeseasonswerefoundtohavethe highest level of Leq levels in winter when the levels of Leq exceededbyanaverageof42%to62%.Thestudyfoundthat S1 had the highest level of Leq in winter (80.80); all other stations measured lower levels specifically S4 and S5. The reason for exceedance can be attributed to continuous vehicular movement, frequent horn use, commercial businessesalongtheroadsidefromthemovementofpeople on the street, the transporting of people on the street, urbanizationoftheareanearbyandlittleenforcementofthe SilentZoneRegulatoryGuidelines.Theoverallconcentration of continuous noise is impacting the Silent Zone area as a resultoftrafficcongestionandcommercialactivityaround sensitiveareas.
3.1.2 Residential zone:
ItwasfoundthatalltheResidentialZonelocations(R1–R5) analyzed, had noise levels exceeding the Central Pollution ControlBoard(CPCB)permissiblelimitof55dB(A)during allseasons;theR5 locationhadthemaximumlevelofLeq of 77.7 dB(A) during the rainy season; this represents an exceedanceof41.4%,whiletheR2 locationwasobservedto havetheminimumlevelofnoise;theaveragelevelofnoise washigher for rainyandwinterseasonsthanforsummer season.Themostsignificantcontributorstoexcessivenoise included heavy vehicular traffic, traffic congestion, mixed land use, commercial activities along roads, pedestrian activity,classesforprivatetuition,andrapidurbansprawl. Overall, significant levels of noise pollution existed in residential areas as a result of increased density of traffic andotherhumanactivities.
3.1.3 Commercial zone:
TheanalysisofCommercialZones(C1-C4)showsthatnoise levels were above the CPCB allowable 65 dB(A) for all Seasons.C2hadthehighestrecordedLeqvaluesof86.0dB(A) duringtheRainySeasonandexceededtheallowablelevelby 32.2%.Overall,theRainySeasonproducedthehighestnoise level across all Commercial Sites. The major sources of excessive noise in the Commercial Zones were heavy vehicular traffic, congested markets, roadside vendors, signalized intersections, loading/unloading activity's, congestion,andhigh-volumeofpublicmovement.Basedon theseresults,theCommercialZoneswerefoundtohavethe

Transport zone:
TheTransportZonelocation(T1toT4)analysisindicatedan excess of the CPCB prescribed 65 dB(A) commercial area noiselimitforallseasons.TheT2 sitegeneratedthehighest noise levels averaging approximately 77 dB(A) Leq specificallyduringthemonsoonseasonandwiththehighest maximum exceedance. The winter season exhibited generallyhighernoiselevelscomparedtootherseasonsas well, which can be attributed to traffic density causing an increaseincongestionanddecreasedatmosphericdispersal of sound. Key contributors to the noise included the continuous movementofbuses/trains;excessivehonking; large crowds of people in motion; roadside vendors; and nearby commercial establishments. Therefore, transport zoneshavehighlevelsofnoisepollutionfromacombination ofbothheavytransportationactivityandtrafficcongestion, primarilyaroundbusterminalsandrailstations.

CONCLUSION
Ambient noise pollution has been assessed in the Silent, Residential, Commercial, Transport, and Industrial zones of Amravati, and the observed Leq were compared with CPCB permissible limits. The results indicate that in most locations of the Silent, Residential,Commercial,andTransportzones,noise pollution was beyond the given CPCB standards, projectingthatitsurbanstateisseverelypolluted.
Silent zones registered the highest noise limit exceedance, with peak exceedance level ranging around40%–62%aboveCPCBstandards.ThesitesS1 recordedthemaximumexceedanceduringtherainy season(61.4%),winter(61.6%),andsummer(55.1%), while locations S2, S3, S6, and S7 showed exceedance withintherangeof45%–55%.
Therewasalargeexcessiveamountofnoiseabovethe CPCB noise limit of 55 dB(A), with the exceedance lyingbetween13.7%–41.4%.ThesiteR5recordedthe highestexceedanceof41.4%duringtherainyseason, whileR3 andR4 withexceedanceof25%–34%,andR2 withacomparativelylowerlevelofexceedance,within 13.7%–19.1%.
Commercialzonesremainedpersistentlyhighly polluted in every one of the seasons, with exceedancerangingapproximatelyfrom13%–32%. However,C2wasthesitewiththeworstexceedanceof 32.2%,followedcloselybyC3 andC4 withexceedance of around 25%–31%; C1, meanwhile, showed lessexceedancenoiselevelsofbetween13.1%–18.3%.
TheTransportZoneswereallprovedtobeinviolation ofthemaximumallowablenoiselimits(65dB(A)).The amount of time that the Transport Zones are in violationrangesfromapproximately3.5%to18.5%. For example, Transport Zone 2 has the highest percentage of time in violation at 14.1% to 18.5%; Transport Zones 3 and 4 have shown a similar percentage of time in violation at 10% to 17%; and Transport Zone 1 demonstrates the least amount of timeinviolationat3.5%to9.5%.
AlloftheIndustrialZones(I1&I2)wereabletoremain belowtheCPCB'smaximumallowablenoiselimits.
Thewinterseasonwasnotedtohavehadthehighest overallnoiselevelsatmostofthelocations,withthe second highest being the rainy season. The summer season had the lowest overall noise levels. The increasedamountofnoiseduringwinterismainlydue to lack of air dispersion, population density, and increasedtrafficactivity.
The primary contributors to environmental noise pollution in the city of Amravati include: vehicular traffic, excessive/repeated honking, roadside congestion, commercial activities, mixed land use, pedestrian activity, and lack of public education on noisemitigationtechniques.
The need to continue developing effective traffic managementplans,enforcingexistingnoiseabatement regulations, developing greenbelts, developing consistent procedures for honking, and conducting continuous monitoring measures will significantly helptoreducethelevelsofurbannoisepollutionand improve the overall condition of the Amravati's EnvironmentalQuality.
RECOMMENDATIONS
The study's results emphasize the need for targeted improvements:bettertrafficmanagementsystems,stricter enforcementofnoiselaws(especiallyinareasdesignatedas quiet), development of green buffer zones, controls on unnecessaryhonking,communityeducationalprograms,and sustainedmonitoringofambientnoiselevelstohelpreduce noise pollution and improve the environmental quality of AmravatiCity.
