2021年3月5日 · IIC stands for Impact Insulation Class. This is the rating given to flooring assemblies and determines how well they mitigate impact noise (footfall mostly). As opposed to STC, IIC rates the flooring assembly as a whole, not just the material on its own. The different parts of a flooring assembly can include:

2022年12月20日 · IIC (Impact Isolation Class) measures a floor assembly’s ability to absorb impact, structure-borne or vibration sound – like footsteps. It’s represented with an integer, or whole number. A larger number means more impact sound is being blocked.

What is STC, OITC, IIC, and Delta IIC (ΔIIC)? This is the most common rating used in North America for determining airborne sound transmission loss between 125 and 4,000 Hz. This range covers the majority of common noises we hear including speech, television, music, dogs barking, and other similar annoyances.

6 天之前 · STC (Sound Transmission Class) measures how well walls or floors block airborne noise—like voices or traffic—with higher scores meaning better isolation, ideally 50+. IIC (Impact Insulation Class) rates how much impact noise—like footsteps or dropped items—a floor muffles, where 50+ tames thuds and keeps peace downstairs.

2023年7月13日 · 资源摘要信息:"本文档主要介绍如何使用STC51系列的单片机通过两个I/O口模拟实现IIC（也称为I2C或两线制串行总线）通讯，分别作为主设备（Master）和从设备（Slave）。通过Visual Basic编程语言，我们可以编写相关的...

2022年12月8日 · STC is airborne sound, which is a sound that can come from your upstairs neighbor blasting a TV or radio or talking very loudly at each other. However, most buildings already have decent STC performance on their own. The most common noise complaints will come from IIC, which stands for Impact Isolation Class.

2024年3月23日 · IIC（Inter -Integrated Circuit）是 IIC Bus 简称，中文叫 集成电路 总线。 它是一种 串行通信 总线，使用 多主从 （多个主机可以连接多个从机）架构。 IIC使用两根双向信号线进行通信： 一根时钟线 SCL，用于通信双方时钟的同步； 一根数据线SDA，用于收发数据。 IIC总线上所有器件的SDA、SCL引脚输出驱动都为 开漏 (OD) 结构，并且IIC为同步的 半双工通信 方式（第五章的第一节有提到过半双工通信模式哦！ 主机（Master）： 初始化总线的数据传输并 …

2024年7月25日 · Three key ratings—Sound Transmission Class (STC), Impact Insulation Class (IIC), and Delta IIC—provide valuable insights into how well an underlayment will perform in reducing noise. Here’s a brief overview to help you make informed decisions.

2022年9月12日 · 本文介绍了stc8h系列单片机在硬件iic通信中的应用，详细解析了i2c配置寄存器、从机状态寄存器、从机地址寄存器和数据寄存器的使用，并展示了iic从机初始化及中断服务函数的代码实现。
