Watts to db

Since Watts are proportional to Amps squared or Volts squared, db (in power) = 20 log V1/V0 or db = 20 log I1/I0 .

How many dB is a watt?

A given dBW value expressed in dBm is always 30 more because 1 watt is 1,000 milliwatts, and a ratio of 1,000 (in power) is 30 dB; e.g., 10 dBm (10 mW) is equal to −20 dBW (0.01 W).

How many dB is 10 watts?

10 watts = 10,000 milliwatts and 10 log (10,000/1) = 40 dBm Then 40 dBm - 0.7 dB + 13 dB - 137 dB + 11 dB - 1.4 dB = -75.1 dBm.

How many dB is 5w?

dBm	Watts
4	2.5 mW
5	3.2 mW
6	4mW
7	5mW

How many watts is 70 dB?

Power (dBW)	Power (dBm)	Power (Watt)
40 dBW	70 dBm	10 kW
50 dBW	80 dBm	100 kW
60 dBW	90 dBm	1 MW
70 dBW	100 dBm	10 MW

How many decibels is 20 watts?

How Many Decibels (dB) is 20W? The typical amount of decibels that equals 20 watts is 115.4 dB.

How loud is 4 watts?

Watts	Decibels
2	93
4	96
8	99
16	102

How loud is 3 watts?

Rule of thumb double your power you get 3 db louder so 2 w would be 91db so 3 w would be ~ 92 db.

How many decibels is 600 watts?

The loudness or DB level is the measure of SPL level at a distance and decreased with increasing distance on a logarithmic scale. So your 600 watt system might product a 130db and mine can provide 135db.

How many decibels is 100 watts?

One watt=90 dB. One hundred watts, or 100X more power=110 dB.

Is a 72 dB Generator loud?

Generally, generators that produce more than 80 dB of noise are considered to be 'loud'. Generators that produce less than 60 dB noise levels are considered to be 'quiet generators'.

How loud is 10w?

How loud is a 10 watt speaker? In addition to the relevant items Micah mentions, it is good to realise that an acoustic power of 10 W is really high: sound power level 130 dB. The sound (pressure) level at 1 m distance of the speaker is then some 120 dB.

How loud is a 30 dB?

Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB.

How loud is a 50 dB?

How Loud Is 50 Decibels? 50 dB is as loud as a quiet conversation, a quiet suburb, a quiet office, or a quiet refrigerator. Notice the use of the word 'quiet' when describing this noise level? That's because all sounds between 31-60 decibels are considered quiet.

How loud is a 70 dB?

70 decibels is as loud as a washing machine or a dishwasher. It is a moderate noise level. 70 dB noise is not considered harmful to human hearing. However, extended exposure to levels above 55-60 dB can be considered disturbing or become annoying.

How many watts is 98 dB?

-3 dBm	0.0005 W
97 dBm	5.01 MW
98 dBm	6.31 MW
99 dBm	7.94 MW
100 dBm	10.00 MW

How many watts is 95 dB?

For instance, a loudspeaker datasheet provides us with information for the characteristic sound pressure level (1 W/1 m): 95 dB. This means that at 1 watt of power, the loudspeaker generates a sound pressure level of 95 dB at a distance of 1 meter.

Is 70 dB twice as loud as 60 dB?

If we compare the sound level associated with 70 dB with a sound of 60 dB, we find that the 60 dB sound is only half as loud. Furthermore, a sound produced at 80 dB is twice as loud as the 70 dB sound, and a 100 dB sound is 8 times as loud as a 70 dB sound.

Is 200W speaker loud?

Loudness of a 200W system depends on the efficiency of the loudspeakers. High quality small consumer/home subwoofers can easily handle 200W without sounding outrageously loud or breaking.

Is 100W speaker loud?

A (reasonably efficient) 100w speaker, driven by a well-matched amplifier, fed with a suitable signal would be deafeningly loud in a living room, or just about audible in a stadium.
