Making objects touchable and untouchable

Hi,
I am trying to make a soundboard like app. I have 6 objects onscreen and when one is pressed,the others fade out and the pressed object zooms in and plays a sound. When the sound is ended, the object zooms back in place and the other objects fade back in.
Here is my code so far:
display.setStatusBar( display.HiddenStatusBar )
local w,h = display.contentWidth, display.contentHeight
local background = display.newImageRect("bg.png", h, w)
 
playAuto = audio.loadSound("Car_Horn.wav")
autoTime = audio.getDuration(playAuto)
print("Auto ", autoTime, "ms")
playHubi = audio.loadSound("Helicopter.wav")
hubiTime = audio.getDuration(playHubi)
print("Hubi ", hubiTime, "ms")
playZug = audio.loadSound("Train_whistle.wav")
zugTime = audio.getDuration(playZug)
print("Zug ", zugTime, "ms")
playBoot = audio.loadSound("Boat.wav")
bootTime = audio.getDuration(playBoot)
print("Boot ", bootTime, "ms")
playFire = audio.loadSound("Fire_truck.wav")
fireTime = audio.getDuration(playFire)
print("Fire ", fireTime, "ms")
playBike = audio.loadSound("Motorbike.wav")
bikeTime = audio.getDuration(playBike)
print("Bike ", bikeTime, "ms")
 
local auto = display.newImageRect("auto.png", h/3.4133, w/2.56) 
        auto.x = w/4.38857 
        auto.y = h/5.85142

        hubi.x = w/1.32413

auto:addEventListener("touch", touchAuto)

boot:addEventListener("touch", touchBoot)
fire:addEventListener("touch", touchFire)
bike:addEventListener("touch", touchBike)
try to set up a variable that will change upon one touch, so if you touch one object the var will set to false, and all touch functions will check that var to see if its true, and because its false they will not fire
By the way, for optimization you could use arrays and loops to access to all your objets. Similiar result could work with few lines of codes even with hundreds of objects
