BOGOR
FOREWORDCLIENT PROFILEPARKROYAL Rainbow Hills Bogor Resort is located amidst Bogor’s spectacular volcanic mountains and picturesque rivers with convenient access to the stunning 18-hole Rainbow Hills golf course
PT Bahana Bukit Pelangi was to build Park Royal Hotel in Bogor. Therefore ALTA INTEGRA asked to do Acoustic & AV Consultation of ballroom & 9 meeting rooms and Noise Control Test of 6 bedrooms & machinery room.
BACKGROUND
FOREWORDCONSULTATION TARGET
NOISE CONTROL
Prevent noise leakage from the Ballroom to meeting & hotel rooms.

BASIC THEORYPARK ROYAL HOTEL

BASIC THEORYNOISE CONTROLTransmission Loss
Transmission Loss (TL) is a figure which rates the ability of a material to block sound. It is usually measured in 1/3 octave band intervals. Mathematically it is defined as the ratio of the sound energy transmitted through a material to the sound energy incident on the material.
Level Difference
The difference in the space and time averaged SPL (Sound Pressure Level).
LD = L1-L2
L1 = Averaged SPL in the source room
L2 = Averaged SPL in the receiving room
DnT,w : Weighted Standardized Level Difference. Standardized to a standard 0.5 seconds reverberation time and weighted to provide a single figure value. The results will include flanking transmission so the test is for the total transmission between the rooms, not just the partition.
BASIC THEORYNOISE CONTROLSpeech Privacy Class
SPC values can be used to specify the required speech privacy for new construction or to assess the speech privacy of existing closed rooms . SPC defined as the sum of the measured average noise level at the position of a potential eavesdropper outside the room, and the measured average level difference between a source room average and the transmitted levels at the same potential eavesdropper location.
SPC = LD(avg) + Ln(avg)
LD = Level Difference; L1-L2; dB
Ln = Ambient Noise Level; dB
CONSULTATION TARGETPARK ROYAL HOTEL
BOGOR
CONSULTATION TARGETSOUND TRANSMISSION CLASS (STC)A sound transmission class of 55 decibels in all fixed walls, 48 decibels on all ceiling mounted track moveable walls and/or partitions is required, with sound baffles above the ceiling between adjoining rooms (PPHG Design Guidelines)
CONSULTATION TARGETLEVEL DIFFERENCED = L1 – L2L1 = Ballroom, 100 dBL2 = Corridor, 55 dB
DnTw+C = 100 – 55 = 45 dB
With the assumption 100dB noise in the Ballroom, Level Difference needed to meet the requirements is 45dB.
CONSULTATION TARGETSPEECH PRIVACY CLASS
SPC = LD(avg) + Ln(avg)75 = LD + 45LD = 75-45LD = 30dB
Level Difference needed to meet SPC requirement is 30dB
