New Aircraft Noise Rules Highlight the Importance of ASA/ANSI S1.4 Sound Measurement Standards
New Global Aircraft Noise Rules Reinforce the Importance of Accurate Sound Measurement This year, the International Civil Aviation Organization (ICAO) adopted more stringent aircraft noise certification limits for new aircraft designs. The updated requirements, which take effect for future aircraft certifications beginning in 2029, are expected to reduce community exposure to aircraft noise by requiring quieter aircraft designs and encouraging continued advances in aerospace engineering. While much of the attention has focused on the new aircraft noise limits themselves, an equally important aspect is how those noise levels are measured. Accurate, repeatable measurements are fundamental to aircraft certification, environmental compliance, and community noise monitoring. This is where ASA standards play […]
Standards Spotlight Pt. 2: Enhancing Acoustics in Student Gymnasiums and Fitness Spaces
Physical education spaces are naturally noisy environments, filled with the sounds of bouncing balls, running feet, and echoing voices. Without proper acoustical design, excessive noise and reverberation can make communication difficult, causing distractions and even safety concerns. The ASA/ANSI S12.60-2019/Part 4 (R2024) standard offers guidance on optimizing gymnasium acoustics to improve speech clarity and reduce background noise. To effectively manage sound, several soundproofing strategies can be implemented: Acoustic Insulation: Installing insulation in walls and ceilings helps absorb sound waves and limit noise transmission. Acoustic Panels: Adding wall and ceiling panels reduces reverberation and enhances speech intelligibility, especially in high-noise zones like weight rooms and cardio areas. Soundproof Curtains & Doors: […]
Standards Spotlight Pt 1: Why ASA/ANSI S12.60-2019/Part 4 (R2024) is Essential for Physical Education Spaces
Creating Better Learning Environments: The Importance of ASA/ANSI S12.60-2019/Part 4 (R2024) In physical education spaces, clear communication is essential for learning, safety, and engagement. Whether in gymnasiums, pools, or fitness rooms, students rely on verbal instruction to develop skills and participate effectively. However, excessive background noise from HVAC systems, utilities, and external sources can create distractions, making it difficult to hear and follow directions. ASA/ANSI S12.60-2019/Part 4 (R2024) establishes essential acoustical performance criteria and design requirements for these spaces, ensuring that speech remains intelligible and that disruptive noise is minimized. With this standard, schools and facility managers can create learning environments that foster student success while meeting best practices for […]
