Electroacoustic Measurement
Achieving high-quality sound requires detailed analysis of the audio generated during the research and development process.
To accurately reproduce actual sound, numerous factors must be considered.
New electroacoustic devices such as communication equipment, tablets, and speakers must offer added value and multiple features in order to differentiate themselves in a fiercely competitive market and meet international standards for voice communication quality.
Whether users demand open-back headphones or speakers with flat frequency responses, manufacturers must deliver high-quality sound that upholds their brand’s promise.
Engineering for High-Quality Sound Reproduction
In order to achieve superior sound quality, it is essential to analyze the audio produced during the R&D phase.
Faithful reproduction of actual sound requires fine-tuning of many parameters, including distortion, frequency response, and directivity.
Finding the right balance involves extensive testing, automated processes, and effective data correlation.
Thus, ease of operation plays a critical role in conducting efficient electroacoustic testing.
Simulating Real-World Phone Usage
To ensure excellent sound quality, it is crucial to analyze the audio created during product development.
Accurate reproduction of real-world sound involves adjusting a wide range of parameters, such as distortion, frequency response, and directivity.
Finding the proper balance requires extensive testing, automation, and strong data management.
Accordingly, user-friendly operation is a key factor in achieving efficient and effective electroacoustic measurements.
Standards Testing for Telecommunication Devices
Modern communication devices, including smartphones and VoIP terminals, must comply with a wide range of international and national regulations, as well as carrier-specific requirements, to ensure efficient communication across the globe.
These regulations set minimum quality standards for aspects such as call switching speed and voice clarity between devices.
The methods used to test these quality parameters are detailed in various standards documents, such as those from ITU-T, ETSI, and 3GPP.
Our software is designed in accordance with these standards, supporting users in ensuring that no critical elements are overlooked during the testing process.
As a result, developers can confidently meet regulatory requirements, ensuring compatibility and communication efficiency with similar devices worldwide.
