New building acoustics app for smartphones
Aug 23 2018 Read 717 Times
Recognising the growing influence of acoustics on building design and the need to reduce the impact of noise from traffic, industry and neighbours on new housing developments and office units, Svantek has introduced a Building Acoustic (BA) Assistant App to support its Class 1 SVAN 977A or SVAN 979 sound level meters with built-in Bluetooth® interface.
The companion free BA Assistant App’s easy to use format allows users to go from room to room with the sound insulation results available for sending to the end customer immediately.
Svantek’s highly accurate SVAN 977A and SVAN 979 sound level meters offer millisecond spectra logging making them ideal for building acoustics measurements with façade, airborne or impact sound insulation results. In fact, the SVAN 979 is one of the most powerful sound level meters on the market. It has a built-in sine wave, pink noise and white noise generator which helps reduce the amount of equipment being carried.
Developed for Android platforms, Svantek’s BA Assistant smartphone app is easy to install and guides users through the sound insulation measurement procedure in accordance with ISO 16283. Sound insulation results are presented on the display in the form of a report compliant with the ISO requirements. The sound insulation calculation is done automatically once the data files are assigned to rooms in BA Assistant App. The ISO 17 rating of sound insulation in buildings and of building elements is automatically calculated and included in the report templates.
A project containing measurements from the source and receiving rooms for different sound source positions is created during the monitoring period. The project is saved in the memory of the sound level meter along with the measurement files. The user interface allows results to be previewed in the form of time history plots as numerical values. The size of the display of a mobile device makes it convenient to display spectrum views such as 1/3 octave analysis. Svantek’s BA Assistant App enables users to add images and voice comments to the measurement projects.
The App can be used with Svantek’s SP 95 Impact Ball for sound insulation testing in lightweight structures. It is dropped vertically in a free fall from height of 100cm to the surface of the floor. The Drone is a Universal Systems Interface (USI) that allows users to connect sound level meters to the BA App through a Bluetooth® analog output or with a cable using the serial interface. Once connected, the smartphone App will start and stop the signal from sound sources automatically.
Svantek is part of the AcSoft Group which also comprises AcSoft Sound & Vibration, AcSoft Health & Safety and GRAS UK.
