Sound Production Acoustics Measurement

Architectural Acoustics Measurement atau Pengukuran Parameter Akustik Arsitektural diperlukan sebagai informasi awal setelah phase kerja Pre-Design. Atau setelah phase kerja After Constuction untuk melihat konsistensi parameter rekomendasi desain dan hasil di lapangan.

Apabila Anda menemui hall yang diperuntukan untuk percakapan, playback music atau pertunjukan music yang memiliki kejelasan suara yang kurang baik. Untuk menganalisa penyebab kejelesan suara yang kurang pada hall Anda secara akurat, kami menyarankan untuk melakukan pengukuran parameter akustik di bawah ini.
