2023年3月30日 · When people are evaluating building materials and acoustical products for sound reduction, they rely on the sound transmission class or STC rating of the product. By understanding this rating of materials, we know how much sound will be blocked from going through those materials.

Sound Transmission Class (STC ) is an integer rating of how well a building partition attenuates airborne sound. In the USA, it is widely used to rate interior partitions, ceilings and floors, doors, windows and exterior wall configurations (see ASTM International Classification E413 and E90).

Sound Transmission Class (or STC) is an integer rating of how well a building partition attenuates airborne sound. In the US, it is widely used to rate interior partitions, ceilings, floors, doors, windows and exterior wall configurations. Outside the …

2024年6月15日 · Sound Transmission Class ratings, or STC ratings, play a crucial role in creating comfortable living and working spaces by reducing noise levels and improving acoustic comfort. In this blog post, you will learn about the importance of STC, the factors that influence them, and how to improve soundproofing in various environments.

2023年10月23日 · 声音传输等级 (STC) 评级是用于衡量建筑材料或隔板抵抗空气传播声音传播能力的尺度。 评级表示材料或隔板提供的隔音分贝数。 STC 等级根据 ASTM E413-10 标准通过测量不同频率下通过隔板（墙壁、窗户、门等）的声音传输损失 (TL) 来计算。 TL是隔板一侧的入射声压级与通过隔板传输到另一侧的声压级之间的差值。 然后根据频率将 TL 值绘制在图表上，并使用公式计算曲线下的面积。 然后根据计算的最终结果分配 STC 评级。 材料或隔板的 STC 等级 …

2025年3月7日 · Sound Transmission Coefficient (STC) – otherwise known as “Sound Transmission Class” – is the golden standard that evaluates how well a barrier, be it a wall, ceiling, door, or window, reduces airborne sound.

2018年9月17日 · STC stands for Sound Transmission Class. It is the ability of a product or material to reduce the transmission of sound between rooms. It measures how much sound a wall, door, window or ventilation system, for instance, will block noise from getting through to …

STC is a numerical reflection of the sound insulation capability of a building element or partition — or in other words, a measurement of how well any given material is able to block sound.

2023年12月7日 · Sound transmission class ratings are the most common sound reduction measurement and share the best picture of how much sound isolation is provided. When designing a space that will share walls, floors, or ceilings, STC testing helps meet code and client requirements, as well as avoid overheard arguments and issues in office spaces.

4 天之前 · STC stands for Sound Transmission Class—it’s a number from 0 to 100 that shows how much airborne sound a barrier stops. A wall with an STC of 50 cuts noise by about 50 decibels—think a loud conversation dropping to a faint whisper on the other side. ... This matters in multi-level buildings—codes often demand IIC 50 minimum for condos ...
