In the architectural field, acoustic design and the application of new materials are becoming key factors in creating high-quality spaces. As an industry leader, TianGe Acoustic has been committed to promoting the development and innovation of architectural acoustics technology. To promote communication and cooperation in the field of architectural acoustics, TianGe Acoustic has carefully prepared the eighth "Architectural Acoustics Design and New Materials Application" seminar. This seminar will bring together industry experts, scholars, and corporate elites to discuss cutting-edge technologies in architectural acoustics design and the innovative application of new materials, injecting new vitality into the development of the industry.

In the field of architectural acoustics, Huang Xiaogang, founder of TianGe Acoustic, is a pivotal figure. With his years of experience and profound understanding of architectural acoustics, he has led TianGe Acoustic to prominence and recognition as a leader in the industry. This time, Huang Xiaogang will personally explain the history of architectural acoustics and key design principles. For practitioners and enthusiasts seeking a deeper understanding of architectural acoustics, this is undoubtedly a feast of knowledge not to be missed.

Sound Insulation and Noise Reduction Standards and Solutions for "Good Houses"

As an expert in the field of architectural acoustics for many years, Huang Xiaogang has unique insights into the sound insulation and noise reduction of "good houses". This time, he will explain in depth the relevant standards and solutions to provide professional guidance for creating high-quality living spaces.

Huang Xiaogang first clarified the core standards for sound insulation and noise reduction in "good houses". He pointed out that according to relevant national regulations, the sound insulation performance of bedrooms, living rooms (halls) in residential buildings should meet the sound pressure level of external noise entering the room ≤ 35 decibels, and the sound insulation of air sound insulation of household walls and floors should not be less than 40 decibels and 50 decibels respectively. " Behind these figures is a quantitative guarantee of living comfort. When indoor noise is controlled below 35 decibels, people can talk and rest without external interference, and truly enjoy the tranquility of home. "He added that in addition to air sound, the control of solid sound (such as walking upstairs, pipe vibration, etc.) is also crucial. The standardized impact sound pressure level of floor weighting should not exceed 75 decibels, and it needs to be reduced to 65 decibels under special requirements.

Huang Xiaogang shared TianGe Acoustic' systematic approach to achieving these standards. For partition walls, a composite structure of lightweight sound-insulating bricks and damping sound insulation panels is recommended. Leveraging the multi-layered barrier principle of these materials, this significantly increases airborne sound insulation while reducing wall load. For floors, in addition to laying a floating floor system (composed of vibration-damping pads and reinforced concrete slabs) to block the propagation path of solid-borne sound, sound-absorbing cotton and sound insulation keels can also be installed in the suspended ceiling to create a double sound barrier.

In the world of architectural acoustics, reverberation time is a core and mysterious concept, directly influencing our perception of spatial sound quality. The National Centre for the Performing Arts, a world-class example of architectural acoustics, embodies the design wisdom behind it, drawing even greater attention. This time, we are honored to have Professor Li Guoqi, a leading expert in architectural acoustics, provide us with an in-depth lecture titled "The Audible Perception of Reverberation Time + A National Centre for the Performing Arts Interpretation." Under Professor Li's guidance, we are confident that we will uncover the mysteries of reverberation time and appreciate the intricacies of the National Centre for the Performing Arts' acoustic design.

The Secret of Reverberation Time

What is reverberation time? Professor Li Guoqi first clarified the concept of reverberation time for us: "Reverberation time refers to the time it takes for sound to gradually decay in a closed space after the sound source stops generating, until it can no longer be heard by the human ear." In places where communication is primary, such as conference rooms and classrooms, reverberation time should be kept relatively short (typically between 0.8 and 1.2 seconds). A shorter reverberation time reduces sound overlap, making speech clearer and more transparent, ensuring accurate information delivery.

The Legend of Acoustic Design of the National Centre for the Performing Arts

As my country's highest art venue, the National Centre for the Performing Arts has a unique architectural form : a semi-ellipsoidal dome on the exterior and multiple halls with different functions inside, including an opera house, concert hall, and theater. This posed a huge challenge to acoustic design. In order to overcome these difficulties, the National Centre for the Performing Arts' acoustic design team took a series of ingenious measures.

In terms of architectural structure, the designers addressed the issue of sound focusing by installing numerous diffusers within the building. Targeted designs were employed for controlling reverberation time in different halls. For example, the concert hall features extensive wood cladding. Wood has excellent acoustic properties, reflecting sound while also absorbing some high-frequency sounds, contributing to a warm, natural reverberation effect. Furthermore, adjustable sound absorbers are suspended from the ceiling. By adjusting the height and number of absorbers, the reverberation time can be flexibly adjusted to suit the needs of different musical performances.

Acoustic Design and Application of Multi-Purpose Halls

The topic will focus on the acoustic design and application of multi-purpose halls. Due to their diverse functions, multi-purpose halls place higher demands on acoustic design. In this session, Xue Liyuan, a senior designer at TianGe Acoustic, will explain in detail the difficulties and solutions for acoustic design in multi-purpose halls, drawing on practical examples. This includes optimizing the acoustic environment based on different functions and selecting appropriate acoustic materials and equipment. Through this study, we will understand how to create a multi-purpose hall that not only meets conference needs but also delivers impeccable sound quality.
