For fish, whales and other marine animals, underwater noises from blasts can cause acoustic trauma and even death. Construction or shipping noise may not kill the animals directly, but it can disrupt their ability to communicate with each other.
For example, marine mammals were more likely to be killed by blasts at lower frequencies, while birds and fish were killed at higher frequencies. The researchers also found a correlation between the number of blasts and the amount of time the animal was exposed to the noise.
In other words, higher frequency blasts were associated with longer exposure times and higher mortality rates.

Are fish sensitive to sound?
Fish is extremely sensitive to low-frequency vibrations, below some 10s of Herz. fish swim away from the sound source if it is sufficiently intense. The fish are trying to avoid being eaten by the predator by making low frequencies of sounds. In the case of fish, it is also possible for them to detect the presence of other fish in the area.
Fish can also be trained to respond to certain sounds. For example, a fish that has been conditioned to associate a certain sound with food may be more likely to eat it if it hears it coming from a nearby source of food.
Can fish get stressed by noise?
Goldfish are susceptible to stress and hearing loss. Hearing generalists, or fish with higher baseline hearing thresholds, are less likely to be affected by noise. However, it is important to note that our results do not imply that all fish are sensitive to the same level of noise exposure. For example, some fish may be more sensitive than others to low-frequency noise, while others may not be sensitive at all.
In conclusion, the results of this study suggest that fish exposed to high levels of low frequency noise may suffer from hearing impairment. It is possible that this is due to a combination of factors, such as age, sex, diet, and environmental factors. Further research is needed to determine the exact mechanisms by which noise affects fish hearing.
Does music affect fish?
If you have ever thought that your goldfish won’t respond to music in your room, it’s time to think again. Many people don’t know that fish respond to sound and can tell the difference between genres of music.
In a new study published in the Journal of Experimental Biology, researchers at the University of California, Davis, found that the ability of fish to distinguish between music and other sounds depends on the frequency and amplitude of the sound. In other words, fish that are exposed to high-frequency sounds, such as music, are more likely to be able to differentiate between the two types of sounds.
The researchers believe that this ability may be related to their ability to detect vibrations in their environment, which may help them to find food and avoid predators.
Does loud TV bother fish?
It can affect the fish, i had to move one of my speakers as it was too close to the tank and it made some of the fish jump about. Rated 5 out of 5 by Anonymous from Great product! I bought this product to replace my old one. It is very easy to install and works very well. I am very happy with it.
Can fishes feel pain?
The fish do feel pain. It is still a kind of pain, but it is likely different from what humans feel. High temperatures, intense pressure, or a sharp blow to the head can be detected by the fish’s nociceptors. When a fish feels pain, it releases a chemical called histamine. Histamine binds to receptors on the surface of the fish’s skin, causing the animal to feel a burning sensation.
This is the same chemical that causes humans to sneeze when they are exposed to heat or cold, and it’s also what causes the sneezing of dogs and cats. Fish also have receptors for chemicals called endocannabinoids. These chemicals are produced by the body in response to a variety of stimuli, including heat and cold.
They are thought to play a role in regulating body temperature, as well as in the regulation of mood, appetite, sleep, pain and other bodily functions. Fish are also known to secrete a hormone called gonadotropin-releasing hormone (GnRH), which stimulates the release of estrogen and progesterone from the pituitary gland into the bloodstream.
