Abstract
<p>Optimal teaching or learning activities require a conducive and quiet environment because the high concentration required on its process. Campus area requires a quiet and silent environment. It is difficult for the urban areas to get a quiet campus environment. The study tries to reveal the evaluation on how the noise factors that occur during teaching and learning process. The study was conducted at Semarang University. The research method used is descriptive analytic method. Research shows that the building of engineering faculty (the A building) at Semarang University shows the proper noise level in line with the standard (School Acoustic Quality Standards). Besides, Semarang University must establish rules and policies to control the noise levels, to intensify the comfort of the lecture process. Based on the research results, the noise level on the Engineering faculty building of Semarang University has not been in line with the predetermined standard, which is more than (55 dB).</p><p>Keywords: noise, lecture activities, acoustic quality standards of school buildings</p>

Summary
Salah satu sarana yang paling penting dalam kegiatan belajar mengajar mahasiswa adalah ruangan kelas. Berdasarkan Gambar 1, persamaan perubahan gelombang bunyi dapat dituliskan : Px = P sin (kx − ωt). Ada dua besaran yang biasanya diperoleh dalam bunyi yaitu frekuensi dan amplitude. Frekuensi adalah jumlah variasi tekanan per detik yang dinyatakan dalam satuan Hertz (Hz), sedangkan amplitudo adalah besaran yang menunjukan kuat lemahnya bunyi. Intensitas bunyi adalah waktu rata-rata aliran energi bunyi per satuan luas dengan arah tegak lurus terhadap bidang yang ditunjuk dan dinyatakan dalam satuan Wm-2. Aras tekanan bunyi dinyatakan dalam decibel (dB) dengan persamaan: SPL 20LOG10 (P Pref ). Berdasarkan persamaan (2.4) akan diperoleh hasil dlam satuan decibel (dB), kemudian penentuan rata-rata aras tekanan bunyi di semua jangkauan frekuensi menggunakan persamaan: SPL = 10 Log
