We have developed a system for measuring passive acoustic requirements

To test the sound insulation of buildings we use sound sources that meet the specific requirements of the ISO technical standards. The system integrates the most advanced features required for this type of equipment.

DF01_DIR - Dodicifacce

Easily transportable Sound box

Thanks to the use of the amplifier (optional DF01_A), it’s able to produce a sound pressure level sufficient to perform the tests and acoustic tests necessary to control the acoustic performance of buildings.

The DF01_DIR sound box is easily transportable via the soft bag with shoulder strap for transport.

The DF01_DIR speaker can be used with other external amplified sources, complying with the specified technical specifications (maximum sound power is not guaranteed).

The passive directional speaker is equipped with a rigid and ergonomic wooden structure treated with embossed paint that protects it from impact and moisture.

Safe srl
We help redefine the relationship between people and workplaces

We believe there are no generic solutions to specific problems, which is why we spend a lot of our time designing and engineering our ideas, services and related innovations. With the care and passion of a craftsman, we build solutions, engineer products, give life to our ideas and those of our customers.

From this commitment was born '12dodicifacce', the engineering division of Safe S.r.l. able to design, build and install multipoint and multichannel sound level and vibrometric monitoring systems, ideal for measuring physical agents inside and outside industrial plants, production areas, construction sites, road and railway infrastructures.

These advanced systems allow the publication of data in real time on FTP servers and Web pages. They are also able to manage alarms, warning systems to avoid or prevent critical situations. '12dodicifacce' creates and markets multiple technological solutions in the field of Acoustics and Sound reinforcement.
