ISO 7779 Measurement of Noise Emissions from Aircraft Equipment
The ISO 7779 standard is a pivotal document for aerospace and aviation testing, specifically addressing the measurement of noise emissions from aircraft equipment. This service is essential to ensure that all aircraft components meet stringent noise regulations set by aviation authorities worldwide. The primary aim is to minimize noise pollution during takeoff and landing, which can significantly impact communities living near airports.
The standard provides comprehensive guidelines on how to measure noise levels accurately using a sound level meter and octave band filters. It also specifies the test conditions under which measurements should be taken, including environmental factors such as temperature, humidity, and wind speed. Compliance with ISO 7779 is crucial for manufacturers who wish to achieve certification from aviation authorities like the Federal Aviation Administration (FAA) or European Union Aviation Safety Agency (EASA).
Testing aircraft equipment in accordance with ISO 7779 involves several steps. First, the equipment must be installed under controlled conditions within a soundproof chamber. This ensures that external noise sources do not interfere with accurate measurements. Secondly, the equipment is operated at various power settings to simulate real-world usage scenarios. Thirdly, continuous and intermittent noise emissions are measured over specific intervals as defined by the standard.
Accurate measurement of noise emissions is vital for several reasons. Excessive noise can lead to hearing damage among flight crew and passengers if not controlled properly. Additionally, it affects the overall passenger experience by creating a more comfortable environment aboard aircraft. Compliance with ISO 7779 helps manufacturers ensure that their products meet international standards, thereby enhancing brand reputation and marketability.
The process of measuring noise emissions from aircraft equipment is highly technical and requires specialized knowledge. Our laboratory uses state-of-the-art equipment to perform these tests according to the latest versions of ISO 7779. We employ experienced engineers who are well-versed in all aspects of aerospace testing, ensuring accurate results every time.
To summarize, compliance with ISO 7779 is mandatory for any manufacturer seeking certification from aviation authorities. By adhering strictly to this standard during the testing process, we can provide reliable data on noise emissions that meet regulatory requirements and contribute positively towards reducing environmental impact.
