![]() Elbow room is sparse, so I wouldn't goto Decibel with a group larger then 4. Once seated, you find yourself in a dimly lit room, ' intimately' packed together. Otherwise, you get a gruff frowning waiter. Inside is a montage of Japanese artwork and sake memorabilia, roped off waiting area, and, if you're lucky, a cute smiling waitress with orange hair. Still, it makes me feel 1337 buzzing myself in. As far as I can tell, anyone who hits the buzzer gets let in during its hours (10 pm ~ 4 am). To get in, you have to walk down a flight of stairs to a basement entrance and hit a buzzer. It is located in the East Village near Astor Place. Therefore, saying rustling leaves correspond to 20dB SPL means that the sound of rustling leaves is 20dB, or 100 times, louder than the quietest sound a human can hear.Ī great Japanese sake bar in NYC, with a lot of character. Thus, 0 dB SPL is the threshold of human hearing. When people say a sound was a certain number of decibels they are implying dB SPL which means "decibels - sound pressure level." The reference for dB SPL is a sinusoid at 1000 Hz which is just barely audible. dBm is another common unit which means "decibels relative to one milliWatt."īack to decibels of sound. For example, the unit dBW means "decibels relative to one Watt." Thus you could say our 60W bulb uses 17.8dBW of power, and the 600W bulb uses 27.8dBW. In the cases where a decibel is used as an absolute unit (not as a ratio), one of the power levels (P 1) is an assumed reference. Then the ratio of these power levels can be expressed as:įor example, you could say that a 60W light bulb uses 10dB more power than a 6W light bulb, and a 600W light bulb uses 20dB more power than the 6W bulb but it uses 10dB more than the 60W bulb. It is commonly used to measure electrical power and the power in a sound. The decibel ( dB) is actually a ratio of two amounts power.
