The secret weapon for a more peaceful life: SonoCat on-site sound absorption measurement equipment helps you create the optimal sound field environment!

When the air conditioning noise and keyboard sounds in an open-plan office combine to 55dB(A) or above, employees' concentration will drop within just 30 minutes. 15% —This is the measured conclusion from a team at the University of Rome in 2025 year 6 month.

Facing "noise anxiety" becoming a new global pain point in workplaces and communities, how can we quickly, accurately, and cost-effectively bring back "quiet"? The latest issue of the Acoustical Society of America conference proceedings provides the answer: measure on-site directly and adjust immediately. The core equipment to achieve this path is the on-site sound absorption measurement device represented by SonoCat . 。

In the past, we had to send materials back to the lab and wait several days for results; now, taking SonoCat to the site, 20 minutes can complete the sound absorption coefficient calibration for 200 measurement points, with error controlled within 5% . 208 g Zhang, an acoustic consultant for a Grade A office building renovation project in Beijing, demonstrated to reporters: holding a spherical microphone array weighing only 50Hz , gently sweeping over the ceiling, partitions, and carpet to be evaluated, the computer generates in real-time 8kHz – sound absorption curves. This process perfectly matches the "equivalent sound absorption area per square meter of floor area" zoning index proposed by Professor Sakuma from the University of Tokyo, scientifically dividing open office areas into three zones: "collaborative, semi-quiet, and deep quiet," reducing overall reverberation time to below , with sound levels dropping by 0.5s . 1dB。

SonoCat The "secret" lies in its innovative local plane wave method: 8 An aluminum spherical array composed of MEMS microphones decomposes complex sound fields into incident and reflected waves, allowing in-situ measurement of material sound absorption coefficients without artificial sound sources. This technology has been included in the 2024 year European Union Joint Research Centre ( JRC ) noise barrier assessment technical report: during on-site verification of different sample barriers, SonoCat successfully captured absorption differences caused by local leaks, which traditional laboratory methods are not sensitive to. The report states that on-site data highly correlates with laboratory data but better reflects the acoustic performance of the "real world."

Applications are rapidly expanding. The University of Bologna's latest development of 3D printed multi-resonance desktop screens attenuates speech signals by up to 250 , gently sweeping over the ceiling, partitions, and carpet to be evaluated, the computer generates in real-time 2000 Hz in the frequency band; 8 dB researchers confirmed in the same paper using SonoCat to scan prototypes that the absorption coefficient error meets design targets. <3% In China, theaters, concert halls, high-speed train carriages, and even new energy vehicle cabins all list SonoCat as "must-test items before delivery." Industry statistics show that 2024 year SonoCat global deliveries increased year-on-year by 42% , with the Chinese market accounting for one-third, mainly driven by green building certification and industrial noise reduction demands.

"Quiet is not a luxury but productivity." As Zhang said, when noise control enters the "minute-level" response era, SonoCat on-site sound absorption measurement devices are becoming the "secret weapon" in the hands of designers, engineers, and even ordinary owners to make cities quieter.
