Vibro-acoustic Technical Certifications

October 31, 2024

After over thirty years of experience in producing Hi-Fi furniture and speaker stands designed to improve the performance of Hi-Fi components, thanks to globally recognized anti-resonance vibration damping systems, Solidsteel has decided to take a step forward. Supported by countless feedback from customers and industry professionals, the company has embarked on a journey of scientific validation of its products' performance.

In collaboration with Prof. Eng. Dario D’Orazio, a professor of acoustics at the Mechanical Engineering department of the University of Bologna, and his research team, in-depth technical studies have been conducted. These studies aimed to analyze the vibro-acoustic characterization of the S5-3 and HF-4 electronics tables, representative models from the Solidsteel catalog, along with the iconic SS series speaker stands.

Detailed Vibro-acoustic Analysis

The analysis was conducted to identify the descriptive parameters of the vibro-acoustic behavior of the systems under real usage conditions, with particular attention to the construction materials. This allowed for a precise evaluation of the consistency between the quality of the system's performance and the cost of the item.

S5-3 and HF-4 Tables

The S5-3 and HF-4 tables were placed inside the listening room of the electroacoustics department at the University of Bologna. The frequency response was measured using a pair of accelerometers placed on various components of the furniture. To replicate real usage conditions, both mechanical impulsive stress, generated by an instrumented hammer blow, and aero-acoustic stress, obtained through a frequency sweep emitted by the room's audio system, were applied.

The results showed that both tables ensure proper decoupling between the shelves and between the structure and the floor.

SS Series Speaker Stands

The SS series stands were also subjected to a vibro-acoustic analysis to evaluate their performance, highlighting strengths and areas for improvement. A loudspeaker was placed on the stands, reproducing a frequency sweep, while the frequency response was measured using accelerometers placed on different elements of the stands. This setup allowed for the replication of real usage conditions.

The results showed that the stands effectively decouple the loudspeaker from the structure, reducing signal transmission by approximately 10-15 dB, especially at low frequencies. The high structural rigidity, due to both the geometry and materials of the stands, is the main factor responsible for the excellent performance.
