  4. 4. FOREWORD CLIENT PROFILE PARKROYALRainbow 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
  5. 5. FOREWORD CONSULTATION TARGET NOISE CONTROL Prevent noise leakage from the Ballroom to meeting & hotel rooms.
  6. 6. FOREWORD Concept and Budgeting Phase: ◦ Architectural Acoustic Concept ◦ Building Noise Control Concept Design Phase: ◦ Architectural Acoustic (EASE) ◦ Building Noise Control Tender/Offering Phase: ◦ Tender & Review ◦ Recommendation of Product & Supplier PROCEDURES Construction Phase : ◦ Supervision / Annual Control ◦ Technical Meeting (with other consultants and CM) Testing & Commissioning Phase: ◦ Testing, measurement, documentation ◦ Report

  8. 8. BASIC THEORY NOISE CONTROL Transmission 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.
  9. 9. BASIC THEORY NOISE CONTROL Speech 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

  11. 11. CONSULTATION TARGET SOUND 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)
  12. 12. CONSULTATION TARGET LEVEL DIFFERENCE D = L1 – L2 L1 = Ballroom, 100 dB L2 = 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.
  13. 13. CONSULTATION TARGET SPEECH PRIVACY CLASS SPC = LD(avg) + Ln(avg) 75 = LD + 45 LD = 75-45 LD = 30dB Level Difference needed to meet SPC requirement is 30dB
