What will be the frequency of an object with 70 decibels as loudness?

Well, with any frequency, you would technically get the same volume, which means that either way,
50Hz \
89.6Hz/ = 70 dB
But with human hearing, it varies, since we cannot hear very high pitches, as you climb the frequency scale, the volume will drop until it becomes inaudible.
So it really depends on whether you are going on human hearing or actual volume.

What is the loudness of a normal conservation?
A normal conversation has a loudness (decibels level) of about 60 dB. As iy approached 70 dB it would be come loud.
How many decibels is a loud noise?
Loudness has to do with the sensitivity of the ears of an individial. The question belongs to psycho acoustics and is not easy to answer.AnswerLoudness depends on the volume and intensity of the sound. A deaf person cannot hear and thus has insensitive ears. Her ear insensitivity has no effect on the loudness of a nearby boombox.A decibel is a logarithmic scale of loudness used to measure the strength or loudness of a signal. Your noise would need to be measured in order to determine its value in decibels.A whisper is about 20 decibels. A sound measured at around 120 decibels would border on pain. Normal conversation measures at about 60-70 decibels.
Decibels of human voice?
Loudness of normal adult human voice is about 70 db at three feet according to http://www.businessdictionary.com/definition/decibel-dB.html
Which is louder 60 or 70 decibels?
40 dB gain change should give about the ratio of 16 for sensed volume and loudness, 40 dB gain change gives the ratio of 100 for measured voltage and sound pressure and 40 dB gain change gives the ratio of 1000 for calculated sound power and acoustic intensity. Go to the link: Subjectively perceived loudness (volume), objectively measured sound pressure (voltage), and theoretically calculated sound intensity (acoustic power).
How many decibels does a cough produce?
70-100 decibels
What is the equivalent db level when listening to earphone or headphone volume?
dB is short for Decibel, or one tenth of a bel. Bels and decibels are unlike any other measurement, because an addition of ten means double the loudness of the noise. For example: 60 decibels is the noise generated from a regular conversation, however, 70 decibels is double the noise; and 80 is double that.
Is 8.9 decibals high?
yes it is... its almost high enough to make you deaf.........LOL! 8.9 decibels is very, very quiet. It is quieter than a whisper. 70 decibels is loud. 140 decibels is painfully loud.
What does 60 decibels sound like?
Go through the chart at the link below. Scan the whole chart; some levels are described more than once. Normal conversation is about 60 decibels, and ordinary piano practice is between 60 and 70 decibels.
What is the decibel level of an average rooster's crow?
An average rooster's crow is approximately 90 decibels. This is about as loud as a dog barking. Chickens themselves average 60-70 decibels, which is on par with human conversation.
What are two types of sound and their approximate decibel levels?
A normal conversation is about 70 decibels (dB). A gun firing off is about 140 dB.
What is the average frequency of intercourse for male aged 65-70?
Twice a week.
What would a small bird singing be on a decibel scale?
That depends how close you measure to the beak of the bird. The closer - the louder! The distance is very important if you measure with a sound pressure level meter.
