Do You Know? Acoustics is not only about sound propagation in the air, but also its propagation in the water. The study of sound propagation and how it behaves in water is called underwater acoustics. Underwater acoustics is a branch of science, and it has become a technology that has been used since World War I. Even before that, in 1490, Leonardo da Vinci has stated his theory in an article “if you stop your

Tahukah kamu? Ilmu akustik tidak melulu tentang perambatan suara dan atau bunyi di udara, perambatannya di air juga sangat menarik untuk dibahas. Ilmu yang mempelajari tentang perambatan suara di dalam air dan bagaimana perilakunya di air disebut dengan underwater acoustic. Ilmu akustik bawah air merupakan cabang ilmu dan teknologi yang telah digunakan sejak perang dunia pertama. Bahkan jauh sebelum itu, pada tahun 1490, Leonardo da Vinci telah menyatakan teorinya dalam sebuah tulisan “Jika anda menghentikan kapalmu di

Bunyi/suara merupakan kumpulan sinyal acak yang memiliki karakteristik fisis tertentu yang bergantung pada sumber bunyi. Salah satu karakter fisis bunyi dapat dilihat dari spektrum yang terbentuk. Ada banyak kebisingan yang dapat dibedakan berdasarkan karakter spektrumnya, seperti White Noise, Pink Nopise, Brownian Noise, Blue Noise, Violet Noise, Grey Noise, dan lainnya. Pada umumnya yang sering digunakan adalah White Noise, Pink Noise, dan Brownian Noise baik dalam pengukuran ataupun pengetesan audio. Banyak orang sangat familiar dengan White

Sound is a collection of random signals that have certain physical characteristics that depend on the sound source. One of the physical characteristics of sound can be seen from the spectrum formed. There is a lot of noise that can be distinguished based on the spectrum character, such as White Noise, Pink Noise, Brownian Noise, Blue Noise, Violet Noise, Gray Noise, and others. In general, what is often used is White Noise, Pink Noise, and

Scientists at Lancaster University and the University of Oxford have created a nano-electronic circuit which vibrates without any external force. Using a tiny suspended wire, resembling a vibrating guitar string, their experiment shows how a simple nano-device can generate motion directly from an electrical current. To create the device, the researchers took a carbon nanotube, which is wire with a diameter of about 3 nanometers, roughly 100,000 times thinner than a guitar string. They mounted
