Jakarta Air Quality Emergency
According to the World Air Quality Report 2020 by IQAir, public awareness of air quality in Indonesia is starting to increase.1 People feel that air pollution is a problem that violates human rights to be able to live in a safe, clean, healthy and sustainable environment.2 Improving the quality of healthy life becomes an urgency […]
HISTORY AND COMPARISON OF BUILDING ACOUSTIC NOISE RATINGS
Indoor noise ratings have a long history. This evolution began with designing instruments that could measure sound repeatedly. Frequency discrimination against octave band sound measurements paved the way for advances in understanding the impact of noise on communication and hearing. The methods currently used in the literature for room noise rating include: Noise Criteria (NC), […]
HISTORY AND COMPARISON NOISE RATING IN BUILDING SPACES
Noise ratings in building spaces have a long history. The first step in this evolution was simply to design an instrument that could measure sound repeatedly. Frequency discrimination of octave band sound measurements paved the way for advances in understanding the impact of noise on communication and hearing. The methods currently used in the literature […]

Differences Between Appointing a Consultant and Design-Builder From the Beginning of a Project
Suppose you want to start a construction project. In that case, you may choose between appointing a multi-disciplinary design consultant first with the design-tender-construction process or directly appointing a specialist design-builder–commonly known as merely a contractor in Indonesia–from the beginning. The same option is also available for any building physics project, either it is architectural […]

Lesson 7: Reverberation and Echo (201912A)
Lesson 7 Reverberation & Echo Did you ever wonder why sound in big halls decays longer than that in bedrooms? This phenomenon has something to do with the ability of sound to be reflected or diffused. In this lesson, we will discuss with you why and how the sound can have such a long decay. […]
Lesson 6: Behaviors of Sound in Rooms (201912A)
Lesson 6 Behaviors of Sound in Rooms To create high sound quality for music venues or speech listening rooms, we need to learn the science behind sound behaviors. Some behaviors can improve or degrade sound quality inside a room. It depends on how you control those behaviors so that the sound waves can act the […]
Lesson 5: Noise Control Performance Indices & Ratings (201912A)
Lesson 5 Noise Control Performance Indices & Ratings In building acoustics, there are numerous noise control strategies to reduce the background noise level to the targeted noise criteria (NC) or dBA–the unit for the overall A-weighted equivalent sound pressure level. Since noise control measures vary in multiple aspects, one lesson is clearly not enough to […]
