Simple answer: It depends on how much time you want to spend moving that mass one meter. Complex answer: A watt is a measurement of power. By definition, P = F*d, where P is the power in watts (W), F is the force in newtons (N), and d is the displacement in meters (m). By substituting the familiar equation, F = m*a, we get P = m*a*d, where m is the mass in kilograms (kg) and a is the acceleration in meters per second squared (m/s2). Furthermore, a = dv/dt, where dv is the change in velocity, measured in meters per second (m/s), and dt is the total time taken for the velocity to change, measured in seconds (s), and dv = d/dt (d being the displacement and dt being the change in time once again). So, a = d/dt2, and P = m*d2/dt2. Knowing the mass of the object (1 kg) and the total displacement (1 m), we can work out a general formula for the power, dependent on time. Substituting those values in, we get P = (1 kg) * (1 m)2/dt2, which simplifies to P = 1/dt2. What this means is, 1 divided by the square of the time you wish to spend moving the 1-kg mass equals the power in watts that it will take to move said mass 1 meter.

i have no clue what the answer is..
If you would like to measure how loud the sound is, dB, decibels, would be good. To give you a rough idea, a whisper is about 30 dB, a baby crying loudly about 100 dB. Also, if you like to measure the frequency or the wavelength, you can use Hertz.
Guitar amps are measured in decibels while speaker output can be measured in watts. The relative wattage or output is not as important as that the sound be heard above the sound of the rest of the instruments in the band.
Sound intensity is measured in watts per square meters, but our eardrums are only moved by the sound pressure measured in newtons per square meters or pascals.
Power (Watts)/ Decibels (if the speaker is efficient) 2 Watts = 93 decibels 4 Watts = 96 decibels 8 Watts = 99 decibels 16 Watts = 102 decibels 32 Watts = 105 decibels 64 Watts = 108 decibels 128 Watts = 111 decibels 256 Watts = 114 decibels 512 Watts= 117 decibels 1024 Watts = 120 decibels Some Volumes to Compare 10 decibels = normal human breathing 60 decibels = normal human conversation 110 decibels = power saw, car horn, shouting in ear, 120 decibels = jet aircraft close by, emergency vehicle siren, rock concert
It is exponential. +3 decibels is a doubling of power in watts, while -3 decibels is a halving of power in watts.
The intensities of traveling waves, which includes sound, light, etc., are measured in units of power divided by area. That is, watts per square meter (W/m2 ) or watts per square foot (W/ft2), or any combination of units which is equivalent.
The sound intensity is defined as the sound power per unit area and is measured in watts per square meter. But our ears are sensitive only to the sound pressure, measured in pascals or newtons per square meters. Scroll down to related links and look at "Table of sound levels".

Reference sound intensity Io = 10^−12 W/m² (Threshold of human hearing). Reference sound intensity level LIo = 0 dB-SIL (Threshold of human hearing intensity level). The sound intensity I is measured in watts per meter squared. The sound intensity LI level is measured in decibels (dB).
Power is measured in watts. Watts is also joules per second, newton-meters per second, kilogram-meters squared per second cubed, and volt-amperes.Electrical power
Sound intensity I is measured in watts per meter squared (W/m²). Look at the link: "Conversion of sound units (levels)".
