I hate B9TLs!
-
You know why?
Because the moment one of those idiotic roaring B9TLs get fixed, 2 more start roaring.
I live next to the road and I consider the VSO a quiet bus with a soothing voice. For me to conclude that, you can imagine what I had to put up with. Ok, the exception was when 9889U just appeared on the road and it sounded like a bumboat before it went for an engine overhaul.
I can't imagine another batch of these monsters!
PS: I refuse to believe it when some say the K230UBs are much louder.
Please....the reach of the B9TL's roar is equivalent to the siren of an ambulance. A distance of roughly 200m or more!
-
FAIL.......
Maybe next time,post this in the Bus Observation threadLOCK
-
too bad lor... another 150 coming in...
-
Its starting to get on my nerves coupled with the arrival of the F-15SG.
I think my house value is gonna depreciate.
-
maybe you should consider a home theatre 3D set to drown out the B9TL sounds lor. then you neighbours will be the ones complaining.seriously, do you think bitching in this thread helps? just feedback to the MPs or SBST la.
-
but good thing about roaring B9s is that the A/C and pickup is better than the silent ones.
-
If the noise level is so bad, wonder how the B9TL can pass the drive-pass noise level test by LTA and eventually get the roadworthy certificate to operate on the road.

Oh no man I disagree.The silent ones are actually much better in performance.
Simple conservation of energy should explain that less other factors.
And, ranting is not a sin. Nor do I wish to argue. I don't know whose fault is it that the wonderful quiet B9TL that first arrived years ago entered this state, nor do I wish to point fingers. If you disagree with my assessment, I would not say you're deaf either.
Its simply eff-ing noisy and I wish to let some steam off.

yeah, agreed that the noisy ones are really really irritating. especially the SL 51 ones.

Strange to me that it seems only Volvo buses in SBST's fleet roar as far as type-to-type basis is concerned. It should be due to the design of the radiator.
For all the crappy performance the VO offers, I still would pick the VO for its reliability...
Hmmm.....maybe its breaking-in time for the B9? I hope so. Can you imagine the B9 roaring for its entire life-span? Some which have been fixed roar again only after weeks.
-
I agree to the svc 21 too.
-
How about having Scanias instead.

I would be willing to trade for the K310UD.I especially dislike it when the B9 moves off slowly.....the extended roar is virtually indistinguishable from an airplane struggling to take-off.

I associate the B9 with the GE90... Effing noisy...
VOs with the RR Trent... Ho sey~... -

I don't exactly have a good idea of how a radiator works.....but the B9's roar sounds a lot like a fan is working terribly hard. Like some high bypass ratio engine. -

This is going OT, but you've heard the RSAF F-15SG with their low bypass engines?
Its higher in pitch at higher speeds......but it sounds orgasmic at low speeds.
Come to think of it......since the B9 traces its roots to the Olympian, should I still be surprised that the Volvo DDs roar? But it just gets louder as each new model appears.
-
some B9TLs vibrate like mad
-
you probably stay near the road.
i still prefer B9TLs over underpowered VO3x and B10TLs. B9TLs aircon are much more efficient to top it off.

NEA has rules governing noise emission and smoke emission under Environmental Portection and Management Act (Chapter 94A, Sections 12 (5) and 77) - for vehiclesBelow is an extract from the Act :
PART V
OFFENCES
Smoky motor vehicles
19. — (1) No person shall use or cause or permit to be used on any road any motor vehicle from which any smoke or visible vapour is emitted.
(2) The driver of any motor vehicle found emitting smoke or visible vapour in contravention of paragraph (1) shall be guilty of an offence, and if the driver is not the owner of that vehicle, the owner shall also be guilty of an offence.
Excessive noise
20. — (1) No person shall use or cause or permit to be used on a road any motor vehicle that does not conform to the standard for noise emission specified in the Sixth Schedule for the class of vehicle to which that motor vehicle belongs.
(2) Any person who contravenes paragraph (1) shall be guilty of an offence.
(3) Where a person is charged with an offence under paragraph (1), it shall be good defence for that person if —
(a) he can prove that the noise or continuance of the noise from the motor vehicle was due to some temporary or accidental cause which could not have been prevented through due diligence and care on the part of the owner or driver of the vehicle; or
(b) where the person is the driver or the person not being the owner of the motor vehicle has charge of the vehicle, he can prove that the noise arose through a defect in the design or construction of the vehicle or trailer or through the negligence or fault of some other person whose duty was to keep the motor vehicle or trailer in proper condition or in a proper state of
repair or adjustment or properly to pack or adjust the load of such motor vehicle or trailer, and could not have been prevented through due diligence and care on the part of that driver or other person in charge of the vehicle.
STANDARD FOR NOISE EMISSION FOR NEW MOTOR VEHICLES
1. Motor vehicles of the following classes shall not emit any noise exceeding the following levels specified when measured 0.5 metre from the open end of the exhaust pipe of the
vehicle:
(d) Goods vehicle or bus with engine capacity not exceeding
10,000 cubic centimetres - 103 decibel (A) noise level.
(e) Goods vehicle or bus with an engine capacity exceeding
10,000 cubic centimetres - 105 decibel (A) noise level
STANDARD FOR EXHAUST EMISSION FOR IN-USE MOTOR VEHICLES
1. Every petrol driven motor vehicle that is in use must be equipped with a silencer, expansion chamber or other contrivance suitable and sufficient for reducing, as far as may be reasonable, the noise caused by the escape of exhaust gases from the engine where it is propelled by means of an internal combustion engine.
2. All parts of the exhaust system of any petrol driven motor vehicle must be in good and sufficient condition and comply with the exhaust's requirements.
3. The level of carbon monoxide emitted from the exhaust of any petrol driven motor vehicle must not exceed —
(a) in the case of a petrol driven motor vehicle (other than a motor cycle) registered on
or after 1st July 1992, 3.5% by volume;
(b) in the case of a petrol driven motor vehicle (other than a motor cycle) registered on
or after 1st October 1986 but before 1st July 1992, 4.5% by volume;
(c) in the case of a motor cycle registered on or after 1st October 1986, 4.5% by volume; or
(d) in the case of a motor cycle registered before 1st October 1986, 6% by volume.
4. Every diesel driven motor vehicle that is in use shall not emit smoke of opacity greater than 50 Hartridge Smoke Units (HSU) or its equivalent.
5. Every motor vehicle (whether petrol driven or diesel driven) must not emit any visible smoke or vapour when in use.
For information, please.

Thats cool.....
103 db is rather loud......its about the same noise level as airplanes taking off!

"measured 0.5 metre from the open end of the exhaust pipe of the vehicle" , very close to the exhaust pipe direct.
