STC Serisi Entegreler

The Sound Transmission Class (or STC) is an integer rating of how well a building partition reflects airborne sound. In the US, it is widely used to rate interior partitions, ceilings, floors, doors, windows, and exterior wall configurations. Outside the US, the Sound Reduction Index (SRI) ISO index is used. The STC rating figure very roughly reflects the noise reduction that a segmentation can provide. Two techniques have been employed to improve the sound transmission class and increase soundproofing; Sound isolation and sound absorption. Sound isolation emphasizes blocking paths that can travel using sound cavity walls, adding flexible channels, or using caulking to seal a room. Sound absorption emphasizes adding additional mass to an already separate partition, often using additional gypsum layers or placing rockwool into cavities.

The single number of STC or sound transmission class ratings is how much wall partitions reduce sound transmission. [1] STC provides a standardized way to compare products such as doors and windows made by competing manufacturers. A higher number indicates better soundproofing than a lower number. STC is a standardized theoretical measurement provided by ASTM E413 and E90 with field sound transmission class provided by ASTM E336-97 Annex A1.

The STC number is derived from sound attenuation values tested at sixteen standard frequencies from 125 Hz to 4000 Hz. These Transmission Loss values are then plotted on a sound pressure level graph and the resulting curve is compared to a standard reference contour provided by the ASTM.

Sound isolation metrics, such as the STC, are measured in specially-isolated and designed laboratory test chambers. There are nearly infinite field conditions that will affect sound isolation on site when designing building partitions and enclosures.

Section 1207 of International Building Code 2006 states that separation between dwelling units and public and service areas must achieve STC 50 (STC 45 if field tested) for both airborne and structure-borne. However, not all jurisdictions use the IBC 2006 for their building or municipal code. In jurisdictions where IBC 2006 is used, this requirement may not apply to all dwelling units.

How Our Company Will Help you:

With over years of experience our expert team will help with reverse engineering service to clients around the world.

Reverse Engineering for STC Microcontroller:

With the process of reverse engineering, we will discover the technological principles of STC MCU through analysis of its structure, function and operation. And we ensure you to make a new program that does the same thing without using or simply duplicating (without understanding) any part of the original.

STC MCU Crack or MCU Hack:

With our MCU Crack or MCU Hack service through specific equipment and methods, you will directly get encrypted microcontroller program files for STC Microcontroller, you can copy the program chip or disassemble their reference research.

STC Microcontroller Clone or Microncontroller Copy:

As a leading MCU Clone service provider, we will help you with your any requirement for STC MCU clone. Discuss your microcontroller cloning requirement with us and get your work done.

STC Microcontroller unlock:

Our company have come a long way as a MCU unlock service providers across the world having a formidable reputation within the industry.

STC Microcontroller decryption:

With MCU decryption (attack) for STC MCU, we will directly get encrypted programming document of MCU by certain equipment and method, which could provide for learning, reference and study after copying programming chip or disassembling. After decryption, we could guarantee that the chip sample we offered has the same function with the master chip offered by client, obtain programming document to offer for client.

STC Microcontroller Dumping:

We will transfer the coded program from the compiler (where compiler is a software where we can write, analyze, test and debug the coded program for STC microcontroller.) to the microcontroller memory. The coding or program written for microcontroller is generally in assembly/C language and the compiler generates a hex file which is understandable by the microcontroller. The hex file contains special instructions which are to be transferred to the microcontroller memory and then it works according to the given instruction and program.

STC Chip Code Extraction:

Our team of experienced engineers will help you with chip code extraction for STC Microcontrollers. Get in touch with us your requirement and get your work done.
